Ode to the Clematophile!

By Cheryl Harrison, Master Gardener

I can not claim to be a clematophile (Clematis expert) but I do like Clematis!   Clematis are wonderful perennial flowering plants … many grow as vines, some are more like small shrubs, some are evergreen and some are herbaceous so die back to the ground each winter.  Their flowers come as bell-like or more star-like shapes with sepals that are single or double; some are scented.  And the colours!  They range from white or yellow to pink or red to purple or blue … pale to deep and some are even striped.  Some flowers grow as large as 25 cm (10in) across!  The beautiful clematis blooms are followed by eye-catching fuzzy seed heads.  There are lots of choices in the genus Clematis.

Clematis seed head

Clematis grow in zones ranging from 3-11.  If you are not sure which zone you are in, check here.   Choose a plant from a reputable dealer.  Look for those that have strong stems and are at least 2 years old so that their root structure is well developed.  Most Clematis prefer sun or part shade but like their roots kept cool so mulch or plant another perennial close by to shade the roots.  Plant your Clematis in moist but well drained soil with lots of well-rotted, organic matter (eg. finished compost) added.  Plant the ripened stem (brown, no longer green) about 16 cm (6 in) below the final soil level.  Clematis prefer neutral to slightly alkaline soil.  All new plants need to be watered regularly until they are established and during dry conditions.  Fertilize with an all purpose organic fertilizer monthly but stop when flower buds are ready to bloom in order to prolong bloom time.  You may start fertilizing again after flowering has ended but stop feeding in late summer early autumn.

Clematis on trellis

Pruning your Clematis for the best blooms may seem complicated.  The confusing part for me was that some references refer to groups 1,2,3 and others use group A, B, C  while others will use the species names.  What is important is knowing what you have and then you can determine how to prune.  Read your plant label for pruning directions or if you do not know which Clematis you have:

When does your Clematis flower?

  1. *flowers on old (previous year) wood in early to late spring, early summer.
    *does not need regular pruning – prune to remove damaged stems or to keep your plant tidy and growing within it’s allocated space.  Prune after the flowering period has ended.
  2. *flowers  early on old (previous year) wood and again in late summer on new current year’s growth. 
    *prune to remove damaged or weak stems and the early flower shoots (encourages the second period of flowering) immediately after the early flowering period.
  3. * flowers on current year’s growth in mid to late summer. 
    * prune back all of the previous year’s stems to the lowest pair of live buds in  early spring.

Clematis may suffer from snails, slugs, aphids or mildew.  Clematis wilt is a fungal disease that may result in the sudden collapse of a previously healthy plant.  Cut back affected part of the plant, even right to the ground if necessary, if fungus wilt occurs.  I have to say that I have only ever experienced the odd slug-chewed clematis leaf in my garden just east of Peterborough.

Clematis will grow on a trellis and in a container, through the branches of another shrub or even up into trees.  It may be used as a ground cover and the shrub types look great in the perennial border.  Clematis flowers are lovely and will attract pollinators and provide them with pollen and nectar.

Read plant labels, talk to garden nursery staff  and other gardeners in your area and/or google to ensure that you purchase the clematis that is right for you.  We may not all become clematophiles but we can still have some of these wonderful plants in our gardens!

Joys of Nature and Spring Garden Tasks

By Sharleen Pratt, Master Gardener

April 22nd was Earth Day.  It is a time for reflection on what we can do to help develop a new approach to conservation and it can all start in our own yard. As we experience what we all hope will be our last full shutdown, we need to remain optimistic in the growing interest in gardening with natives and the number of younger people who are learning to grow their own vegetables.  Douglas Tallamy, author of Nature’s Best Hope, writes that as homeowners, we need to “turn our yards into conservation corridors that provide wildlife habitats”.

Spring is a time of renewal.  To help us get through the stressful days of this lockdown, a walk outdoors will help you experience the joys of nature and all it has to offer! 

I have created two lists.  The first is ‘Joys of Nature’ that you will encounter this time of year.  The second is ‘Garden Tasks’ to tackle over the next few weeks.

JOYS OF NATURE

Hepatica image compliments of Joan Harding, Peterborough MG
  • My garden makes me smile this time of year with all the blooming Daffodils (Narcissus), Hyacinths, Hellebores and even Lungwort (Pulmonaria officinalis). 
  • Local ponds are alive with the sounds of the spring peepers and the chorus frogs.  If you take a walk and come across a wetland, you will be amazed at the sound.
  • Many of the migrating birds and waterfowl have returned.  My feeders are being well used by the yellow finches, grackles, house finches and mourning doves.  If you enjoy the hummingbirds, don’t forget to get your feeders out now.  They will soon be back!
  • A walk through the woods will reveal the beauty of the spring ephemerals.  Ephemerals are short-lived spring flowers that take advantage of the sunshine before the trees get their leaves.  I have seen bloodroot, hepatica, coltsfoot and the beginnings of the trilliums and the dog-toothed violets.
  • If you are out digging in your garden, don’t be surprised if a robin will follow you around in the hopes you might throw him a much sought-after worm.  Robins are already nesting so the female is likely to be at the nest site.
  • Watch for early butterflies such as the Mourning Cloaks, Eastern Comma and the Spring Azure.
  • In early May, you should begin to see the white blossoms of serviceberries and the beginnings of the lilacs and the cherry blossoms.

Get outdoors, take a deep breath and walk slowly through a local park or wooded area and enjoy many of the items mentioned above.  Do it now before the return of the blackflies and mosquitoes!!

SPRING GARDEN TASKS

Author’s Spring Garden… Hyacinths, Bloodroot and Daffodils
  • Only rake your lawn if walking on it leaves NO footprint.  The time to overseed your lawn is generally when the lilacs are in bloom.
  • Now is the time to top dress a generous amount of compost and other organic material into your garden beds.  Let the earthworms do the work.  I do not suggest that you rototill your garden as this disturbs the beneficial life in the soil.  Bacteria, mycorrhiza and insects are damaged, sometimes beyond repair, with rototilling.
  • Prune overgrown vines and shrubs such as some hydrangea and some of the clematis; basically all the shrubs and vines that do not bloom in spring.  Do not prune lilacs as they bloom on last year’s growth.
  • Gradually remove protection on rose bushes and prune down to a swollen bud.  Remove dead, diseased and crossing branches.
  • If you haven’t already, now is the time to sow frost tolerant veggies such as peas, carrots, spinach, lettuce, beets, kale and radishes directly into the garden.
  • Divide and transplant perennials as growth resumes.
  • Now is a good time to think about planting shrubs and trees.  Maybe you would like to replace an old shrub with something native, such as Black chokeberry (Aronia melanocarpa), Eastern snowberry (Symphoricarpos albus) or Gray dogwood (Cornus racemosa)
  • Be sure to have your rain barrels set-up and ready to collect that wonderful spring rain.
  • Keep your bird baths filled and cleaned.
  • If you have been growing tomatoes, peppers, cucumbers and annual flowers indoors, early May is the time to begin to harden off those young seedlings.
  • The soil is still quite soft, so now is a good time to edge your garden beds as well as start to pull all those weeds that seem to survive no matter what the weather.

    Get out in your gardens, enjoy the warmer temperatures and don’t forget to get your knees dirty!

In Praise of Spring Bulbs

By Mary-Jane Pilgrim, Master Gardener

Spring bulbs are one of the most rewarding of garden plants. For very little maintenance, they show off their grandeur year after year while announcing the arrival of spring and a strengthening and more powerful sun.

“The more, the merrier” is my motto when it comes to bulbs. From snowdrops to crocus to daffodils to hyacinths to tulips, they all provide a show in the garden for very little effort, and they chase away the late winter browns. You likely have more room for bulbs than you think because you can plant them underneath perennials and shrubs that will hide the bulb foliage while it is dying down in late spring.

Spring bulbs are planted in between September and frozen ground during the year previous, and they spend the winter underground preparing for their showtime when the snow fades away. You’ll find bulbs of all types for sale in that timeframe at your local nursery centre, in supermarkets and in big box stores.

The secret to being able to plant more bulbs each year in the fall is to know what you have growing already and where. This spring: take pictures and more pictures so that you know where these reliable soldiers are and you can then avoid shoveling into an existing clump this summer.

Pictures are also helpful when it comes time to divide those happy but oversized clumps of bulbs. When the flowers begin to decrease, it’s time to divide and replant. The best time to do this is when the foliage has browned in late spring. Dig up the clumps, being careful to dig deep enough so as to not slice them into pieces by mistake. Replant a few immediately and store the rest in a dry place until the fall.

An alternative to pictures is to come up with a “bulb marking system” — I use green metal miniblinds to mark my bulbs. Unfortunately, the miniblinds do travel sometimes so I need to reinstate them in the spring if that has happened. The markers are a visual reminder that although it appears later in the summer that a particular location is bare, it is not and you’ll avoid having to replant those spring beauties.

If you purchased forced bulbs in the supermarket in February (like paperwhites, daffodils or tulips), these can be planted out into the garden that same year. After the greenery has died back, store them in a dry place until the fall and then plant them with other purchased bulbs.

For autumn planting: Choose the site for your new bulbs and prepare the area with compost and bone or blood meal. I usually plant 5 or 6 in a group initially for tulips, daffodils and smaller bulbs like crocus.

If squirrels and chipmunks are bothering your tulips after planting, try cutouts of 1″ chicken wire planted into the soil just above the bulbs. The bulbs will happily grow through the mesh next spring but the critters can’t dig past the wire mesh.

If squirrels are bothering your tulips in the spring, try daffodils instead. You could also try planting allium bulbs with your tulips as they emit an odour that the critters do not like. Other suggestions are some raw onions cut up and scattered around the bulbs or tall chicken wire cylinders, even if they are unsightly. Might be worth a try.

Lastly, you may also choose to embark on a squirrel-feeding program during bloom time to discourage the striped and bushy-tailed rodents from munching on your blooms in favour of yummy peanuts. Be aware, though, that this may actually encourage more squirrels to your buffet!

The importance of stretching when gardening

Make sure you warm up and stretch like you would for other activities!

By Emma Murphy, Master Gardener

(Disclaimer – The information provided is for general educational purposes only and not intended as medical advice; please discuss your personal situation with a medical professional)

The last time I was at my physiotherapist she said that more than half the cases she sees in April and May are related to gardening and sports injuries. People rush into doing things too quickly and most injuries could have been avoided by simply stretching properly to warm the body up.

“The secret to a healthy garden is a healthy gardener.”

Canadian Physiotherapy Association

Gardening is wonderful for your physical, mental, and emotional health, but if you don’t take care to stretch your body before spending time crouching, bending, and pulling weeds, you’ll end up feeling stiff and sore or potentially injuring yourself. This is especially important at the beginning of the season when we’ve been less active over winter but are overly enthusiastic to get into our gardens and complete all our spring tasks.

A stretching routine before and after gardening helps to minimize muscle imbalances, prevent injury, and improve your ability to garden for longer periods.

A warm up and stretches are critical to avoiding injury, particularly as we get older.

First, take a walk around your garden (or around the block) for 5 to 10 minutes to warm up your large muscle groups. The best stretches prior to gardening are dynamic stretches because they prepare your muscles for the repetitive movements required with gardening. After you finish gardening static stretches are better to improve your overall flexibility. Read more here.

This warm up will raise your heart rate and body temperature, as well as giving you an opportunity to assess your gardening situation and think about your plan for tackling the tasks ahead.

Yawning and stretching at the same time – cats are multitaskers!

Cindy Haynes of the Iowa State University Department of Horticulture has some great advice on preparing your body for the gardening season ahead. Dr. Leonard Perry, Extension Professor at the University of Vermont’s Extension Department of Plant and Soil Science lists a number of stretches in this article.

The SouthEast Wisconsin Master Gardeners teamed up with the University of Wisconsin – Extension department to create this informative body mechanics brochure which includes both stretches and tips for various activities like bending, lifting, and turning.

If you suffer from arthritis, this publication by the U.S. National AgrAbility Project called Arthritis and Gardening contains information about arthritis, how it affects gardening activities, and things you can do to minimize its effects.

A few final words from my own experience:

  • Make sure you always have enough water with you and drink plenty of it, particularly in the summer months. Dehydration can impede your body function and lead to aches and pains. Read more detail here.
  • While doing repetitive activities, limit any one to 20 minutes, then take a 5 minute break and stretch. Then your next activity should not involve the same muscle group. So weed for 20 minutes, stretch, then rake for 20 minutes.
  • After a busy day gardening and completing some static stretches, a warm bath with Epsom salts does the body a lot of good.

Gardening is a great activity for maintaining and improving your body’s range of motion, bone density and muscle strength, and joint flexibility, not to mention the benefits of reducing stress and anxiety, which we are all dealing with during this pandemic.

Nativars and Pollinators

By Lois Scott, Master Gardener

The term “nativar”, while not a scientific term, is being used to describe native plants that have been cultivated by horticulturalists.  So, what exactly is a cultivated plant or cultivar?  A cultivar is a plant that has been bred for specific characteristics such as improved growth habit, specific leaf colour, flower colour, or disease resistance to list a few examples.  Many cultivars are sterile, meaning they do not produce seeds or if they do produce seed, the seed will likely not produce a plant identical to the parent plant. 

The way to identify a cultivar of a native plant or “nativar”, is by looking at the plant name.  If you check out the photos of plant tags, you will see one for the straight species native plant (not a cultivar) that gives both the common name, False Indigo and the scientific name, Baptisia australis.  The other tag is for a Baptisia cultivar named ‘Cherries Jubilee’.  ‘Cherries Jubilee’ is the cultivar name.  The cultivar name is usually in single quotation marks.

There are a number of very important reasons to plant straight species native plants in our gardens including the support of pollinators.  The question is, do native cultivars support pollinators in the same way? 

Annie White, a researcher at the University of Vermont has found “that changing flower size, colour or shape changed the availability and/or quality of pollen and nectar offered by the flower which negatively impacted pollinators” and “the more manipulated the cultivars became, the less attractive they became to pollinators”.  To read more about Annie’s research and results check out this link.  https://pollinatorgardens.org/2013/02/08/my-research/

If you are looking for pollinator-friendly native plants that are not cultivars check out nurseries that specialize in native plants such as Peterborough’s Ecology Park.  https://www.greenup.on.ca/ecology-park/  

When at the garden centre, you will now know how to distinguish a straight species such as Echinacea purpurea (purple coneflower) from an Echinacea cultivar like Echinacea purpurea ‘Razzmatazz’.

Don’t Spring into Spring Clean-Up just Yet

By Anica James, Master Gardener in Training

Spring is finally here, a time for new beginnings. The days are getting longer, birds are singing their hearts out and the snow has melted for the most part, but it’s still too soon to do any kind of clean up in your yard. It may be tempting to get out the rake or leaf blower just because it’s sunny and leaf bags are on sale at your local box store, but we need to hold off just yet for the sake of helping other creatures and pollinator species who are still asleep.

Although we are all anxiously waking up from our own personal winter hibernation–whether it be mental or physical–many creatures around us are still sound asleep in the leaf litter or below the mulch and we should not disturb them just yet. When you clean up your yard too soon, all for the sake of aesthetics or curb appeal, you are essentially removing all of the beneficial insects in your vicinity, like those responsible for making your flowers bloom or for your fruit and vegetable plants to produce food.

Some beneficial pollinators overwinter in the hollow stalks of perennials and under rocks. Examples of insects local to us that are still in diapause state are butterflies (like Mourning Cloaks or Question Marks), lacewings, ladybugs, mason bees and parasitic wasps, which all spend the winter either as pupae or adults hidden away in your yard. Even Luna moths and black swallowtails spend the winter months in cocoons or pupa that look just like a crumpled brown leaf, so be on the lookout for those.

It is best to wait until the temperature is consistently 10 degrees Celsius before you start raking leaves, turning soil, or using a leaf blower. Personally, I like to play it safe with the 10 For 10 rule: 10 degrees for 10 days. This allows nature to take its course and it allows me to have enough time to observe my property and familiarize myself with the various kinds of flora and fauna that emerge post-winter.

If you do decide you feel so inclined to “tidy up” this early, do it with purpose and be mindful of the sleeping and living creatures that are still hidden away. Take your time, look for any signs of beneficial insect stages and either take note and leave it for a later date, or carefully cut and set it aside in a natural area so solitary bees and others insects can still use the refuse for food or shelter. Refrain from adding more mulch because it can trap certain kinds of beneficial bees, beetles and flies that burrow in the ground (almost 70% of Canada’s bee species nest underground). For more information on how to properly “clean up” your yard read Nesting and Overwintering Habitat for Pollinators and Other Beneficial Insects PDF by the Xerces Society.

But again, the best thing to do is wait and to try to remove as little from your property as possible.

So in the meantime, what can you be doing instead of gardening?

  • Get outside, go for walks, enjoy the little things; notice the bulbs emerging naturally and gracefully from the cool earth, poking their way through the leaf litter- now is the time to enjoy the scilla, crocus, pushkinia, galanthus and helleborus
  • Continue to sow vegetable and annual seeds indoors and plan your garden; what are your goals for this year, however big or small?
  • Early spring is the best time of year to be on the lookout for invasive pests and plant species and begin to develop an Integrated Pest Management plan; gypsy moths, garlic mustard, european buckthorn, and goutweed are commonly found throughout the Peterborough area
  • Focus on spring cleaning your tools, your patio furniture, tidying your deck, potting bench or shed; put more focus into the inanimate things
  • Celebrate the beginning of spring by honouring the maple tree, it’s delicious sap and syrup, and the work that goes into providing us all with natural liquid sugar; maybe consider ordering a maple for your own yard
  • Repot indoor plants if needed
  • Read up on and think about ways you can increase pollinator habitat on your property or within your community, no matter the scale

There is so much that you can do while resisting the urge to rake or blow. Relax, enjoy the much needed sunshine that the vernal equinox has brought us after the long winter and try to go at the same pace nature is. Patience will pay off in the long run once you remember that gardening isn’t just about plants.

Great resources for more information about pollinators that spend the winters in our gardens and why we should hold off until mid-April to start yard work:

Permaculture: Use of Zones

By Suzanne Seryck, Master Gardener

I have often heard permaculture referred to as ‘common sense’ gardening and their usage of ‘zones’ as one of their design principles is no exception. However, I have to admit up front that when I designed my previous garden, I had not heard of permaculture and was also unfortunately also lacking in common sense that day! What did I do that would ultimately cause me so much grief over the next 15 years?

We had just over 1 acre and the house was located towards the back of the property, so I decided to place the shed, vegetable garden, herb garden, nursery and greenhouse at the very front of the property. The result was that was pretty well everything that I needed to garden daily was all located as far away from the house as possible.

Shed way at the bottom of the garden
Closer look at shed

At the time I thought I had a good reason for this, keeping the children and pets close to the house. But ultimately when I needed the pruners to prune the hedge at the back of the garden, or I needed some herbs for the supper I was in the middle of cooking, or I was harvesting or watering, I ultimately came to regret my poor planning choice. So, a few years later when it came to finding a location for the chickens, by then I had attended a couple of permaculture courses, and I placed them as close to the house as possible. A location that while waking me up in the morning, ultimately made me pat myself on the back every day in the winter just before putting on all my winter gear to take out their food and water.

Zoning is a permaculture design tool that allows you to design your landscape according to usage and attention required. It is not limited to home gardens, and can be used on almost anything from a large farm to a kitchen design. By designing your garden using zones, you take into account the usefulness or frequency of each element in your garden, and place those elements closer to your location, which is your house. So something that you use daily, such as a herb garden, would be placed closest to the house, along with pots of annuals which require frequent watering and dead-heading. Using the same principle, fruit trees or a meadow garden requiring less maintenance would be placed further away from the house.

Zones are numbered from 0 through to 5, where 0 is the location of the house, and will be different in everyone’s garden. They are typically shaped by topography, soil type, placement of the sun, and the homeowner’s requirements. So while they are often shown in diagrams and books as either exact circles or half circles, they are more flexible often merging into one another.

Most permaculture books describe the following zones:

0 – Home
1 – Areas closest to your house that requires the most attention, harvesting, weeding, dead-heading, herb and vegetable garden
2 – Less intensively managed areas
3 – Fruit and nut trees, twice weekly maintenance
4 – Wild foods and timber, weekly maintenance
5 – Natural area

But again, these zones can be changed according to your requirements.

To start designing using zones, you need to look at each element in your garden according to how often you use the element or how often you need to care for the element. Zones are created based on relationships, our relationship to our garden, and how different elements in our garden connect with each other. It is best to start with elements closest to your house and work outward.

As an example, I have perennial flower beds in the front of my house and also in the back. The beds in the front are full to partial shade, heavily composted with leaves and packed with large leaved plants. I get very few weeds in the front beds and also do very little deadheading. The beds in the back meanwhile are full sun, plants are not placed as close together, they typically need more dead heading, and while they are also heavily mulched with leaves, the leaves typically only last until mid June. My front beds are in zone 3 and the beds in my back garden are in zone 2. Zone 1 in my garden is for annuals and vegetables in pots and hanging baskets surrounding the house that have to be watered frequently.

Permaculture zones are a tool that can be used when designing your garden to make your life easier. In the book Gaia’s Garden, A Guide to Home-scale Permaculture by Toby Hemingway, the author includes a quote from Bill Mollison, the co-founder of Permaculture, offering guidance for where to plant a herb garden.

“When you get up in the morning and the dew is on the ground, put on your woolly bathrobe and your fuzzy slippers. Then walk outside to cut some chives and other herbs for your omelet. When you get back inside, if your slippers are wet, your herbs are too far away.”

And Sow it Begins

By Marilyn Homewood, Master Gardener in Training

The season has begun! Canada Post has delivered seeds for this intrepid gardener to coax into cutting garden participants by providing the right conditions for survival and growth. In order to germinate, seeds need water, oxygen and warmth.  Some like foxglove have additional requirements such as light.  Once sown, seeds soak up water to soften their outer coat (“imbibition”) and then begin to metabolize stored food reserves.  A seedling soon appears.  At my house, seeds are germinated in a warm room and then moved to the sunroom where it is cooler and brighter.  My growing set up consists of a metal cart (two main levels) with adjustable grow lights hanging above the bottom shelf.  When space runs out on the cart, the tables in the sunroom are enlisted. To brush up on seed starting essentials check out the articles in the resources list.

Tips that have come in handy for me are highlighted below:

Online seed starting calculators.  I wish I had known about this before I calculated all my dates this year! Based on your last frost date, the calculator gives you the date to sow your seeds as well as an approximate date for transplanting seedlings outside. 

Sowing tiny seeds:  Gadgets don’t work for me.  This year I discovered pelleted foxglove seed and loved it.  Not only does the pellet make it large enough to handle easily, it is coloured so you can see it on the soil. For non-pelleted tiny seeds, I use a moistened toothpick to pick the seed up from a dish and drop into the plug tray. 

Vermiculite:  Once seeds are sown, covering the tops with vermiculite prevents the formation of a hard crust.  Tiny seeds such as snapdragons and foxglove get barely covered with a fine dusting.

Cold Germinators:  These are hard to start seeds like dara and bupleurum. Some annual varieties fall into this category. Put these seeds into the freezer to stratify for a few weeks. Try to not to forget where you put them.

Consistent Warm Temperature:  Most plants will germinate around 70F.  Bottom heat from a propagation mat can provide faster and more even germination.

Bottom Watering:  Using plug trays or cell packs in trays allows you to water from the bottom. Water wicks up from below reducing incidence of fungal disease and preventing tiny seeds from washing away. Option 2 – use a turkey baster to water small seedlings.  Time consuming but precise.

Supplemental Lighting:  Seedlings need 14-16 hours of good light to develop strong, stalky stems.  Even in the brightest room, the daylength is too short early in the season (February/March).

Succession Planting:  This involves sowing in batches, successively, every few weeks. This spreads out the flowering window and provides blooms over the season.

Low Growing Natives for Lawn Replacement

By Sharleen Pratt, Master Gardener

I recently listened to a talk by Lorraine Johnson who is the former president of the North American Native Plant Society and is the author of numerous books on gardening and environmental issues. I was inspired by her talk and have started plans to turn part of my front lawn into a native garden.

I have struggled for years to grow grass near the bottom of our front yard.  The soil is mostly clay with a lot of rock.  We have no sidewalks and this part of the lawn sits at the curbside where it could be affected in the winter by salt and sand.  It faces north/west and receives a very hot sun, especially in the afternoon.

I am not a regional native plant purist.  I get excited about most plants and have a variety of perennials in my gardens.  I am hoping to fill this garden bed with as many native plants as possible, but I do recognize that some of the plant varieties are not always considered native.

There are a number of lovely native plants for sun that have height, but I am cognizant of the fact that my neighbour requires a safe line of sight to the street when they come down their driveway.  For this reason I would like to use mostly low growing groundcover with a few taller plants positioned in areas that will give a pleasing look to the garden bed, but also not impede on visibility.

I have begun to research native groundcovers and other low growing plants that would survive in the conditions I’ve described and here is what I have found so far.  Some of these are new to me, but others are plants I already have in my backyard.

Have you considered replacing part of your lawn?  I would love to hear about your ideas and your successes and failures.

Bearberry (Kinnikinnick) Arctostaphylos uva-ursi

This plant grows 6 to 8” tall and has a spread of approximately 3 feet and is similar to a low growing shrub.  It has a white bloom with a tinge of pink in May.  It’s drought tolerant once it’s established. Rounded berry-like fruits ripen in August to September.  Birds love the fruit!  I have a friend who has found that this plant will disappear over time and because it prefers a sandier soil, it may not be the perfect plant for my home.  However, I may give it a try as I occasionally enjoy pushing the limits.

Creeping Juniper, Juniper horizontalis ‘Wiltonii’

This plant is known to be salt tolerant, likes sandy soil and full sun, grows to a height of 8” and spreads to approximately 7 ft.  It is a non-flowering evergreen.  It spreads by long trailing branches. Foliage is primarily scale-like (adult) with some awl/needle-like (juvenile) needles appearing usually in opposite pairs. Foliage is typically green to blue-green during the growing season, but often acquires purple tones in winter. It likes to grow over rocks; however, it is a slow grower and takes some time to get established. 

Prairie Smoke, Geum triflorum

Prairie Smoke; Author’s garden

This is a tough plant, and grows to about 6 – 12 inches.  It has a lovely reddish pink to purple bloom with interesting seed heads.  It is drought tolerant.  My one concern is the hot afternoon sun, as my research shows it may prefer a bit of shade later in the day.  As the flower fades and the seeds begin to form, the styles elongate (to 2″ long) to form upright, feathery gray tails which collectively resemble a plume or feather duster.  They are very unique.  It spreads by rhizomes and can be naturalized to form an interesting groundcover.

Small Pussytoes, Antennaria howelli

It has spoon-shaped basal leaves, is known to be drought tolerant, and has flower heads that look like little shaving brushes.  There are three to 15 flower heads in a flat to rounded cluster at the top of the stem. Stems are erect, green to reddish, covered in long, white, matted hairs and sometimes glandular hairs. Horizontal, above ground stems (stolons) emerge from basal leaf clumps, spreading in all directions, rooting at the nodes and forming colonies.

Pasque Flower, Anemone patens or sometimes Pulsatilla vulgaris

Pasque Flower; Author’s garden

Pasque flower grows up to 12 inches tall and forms a rounded clump, which increases yearly. It never gets out of hand, making it a desirable plant.  It carries one flower with purple petals and yellow stamens, on top of each stem.  The bloom is quite large, up to 2 inches in relation to the overall size of the plant.  It is not fussy about soil conditions, but may go dormant during drought.  It blooms in late spring into summer.

Nodding Wild Onion, Allium cernuum

My research shows this is a very pretty plant that grows to a height of 1 to 2 feet.  It blooms in mid-summer.  Its grass-like ribbony leaves are long and graceful; its flower cluster hangs down, covered with a fine onion-skin-like sheath before opening.  The blooms in mid-summer are whitish rose coloured and bell-shaped.  The seed heads are round.  It does prefer good drainage.  Looks best when planted in groups.

Butterfly Weed, Asclepias tuberosa

Butterfly Weed with Zinnias; Author’s garden

This is a butterfly magnet that has clusters of orange flowers borne at the top of 2-to-3-foot stems.  It is probably a little larger than I would like, but thought I might give it a try in the front.  This image is from my garden 3 years ago.  I lost the plant the next year and believe it was because of overcrowding and not enough sun.  The leaves are narrow and dark green.  The plants get bushy if they have lots of room.  The seed pods are large and very striking.  They bloom in mid-summer and prefer a full sun exposure.  Once established, they are drought tolerant.  It emerges from the soil quite late in spring, so it is important to be careful not to disturb the roots.

Winter Bird Treats

By Lois Scott, Master Gardener

I have been fortunate this winter to have the ability and opportunity to carry on with regular, ‘socially distanced’ walks in my neighbourhood and to be able to enjoy the winter interest provided by nature. 

On several walks I was quite excited to see small flocks of Pine Grosbeaks and Cedar Waxwings feeding on ornamental crabapple trees (Malus species) in two neighbouring gardens that I pass by.  For me it was a special treat to see Pine Grosbeaks, as they are a somewhat irregular winter visitor to the Kawarthas.  Their breeding range is in the boreal forest and, according to Drew Monkman, if there is food they stay put. If not they travel south where you may see them on feeders or fruit trees, such as crabapples.  

Crabapples, typically planted for their flowers, produce colourful fruit that is not only attractive in winter but a potential source of food for birds.  In choosing a variety to plant, Landscape Ontario recommends considering resistance to disease and insects, and fruit persistence, which is important for feeding the birds as the crabapples need to stay on the tree. Another noteworthy fact is that birds can be picky eaters and in their estimation apparently not all crabapples are created equal.  For example they like ‘Prairiefire’ whereas they do not like ‘Adams’, ‘Donald Wyman’ or ‘Red Jewel’.  Who knew!  I don’t know what the varieties are of the two different trees I saw birds in but the tree in the first photograph shows the tree fairly well stripped of fruit. In the second photo there is still plenty of fruit that they have not come back to finish. 

Crabapple trees in the author’s neighbourhood

There are other excellent choices of native trees and shrubs that can provide winter food sources for birds.  The hackberry (Celtis occidentalis), a shade tree that works well in ‘difficult’ urban areas, hawthorns (Crataegus species), highbush cranberry (Viburnum trilobum), and red chokeberry (Aronia arbutifolia) are a few good choices.
