African violets are the plants that immediately come to mind when anyone asks me about houseplants. This plant is an old favourite for good reason. I have two. As the name implies, African violets are native to the cloud forests in the mountains of east Africa. Many of the native plants are threatened or endangered due to habitat loss. African violets are not violets (family Violaceae, genus Viola) but are included in the family Gesneriaceae, genus Saintpaulia.
African violets are classified by size from the “Mini” which are less than 7.6 cm (3 inches) in above-ground diameter to the “Giant” which ranges from 30.5 cm – 40.6 cm(12-16 inches). They are pretty plants even when not in flower which they will do almost continuously under good growing conditions. Their flowers may be single, semi-double or even double. This refers to the rows of petals on the flowers. Flower colours include blue/violet, pink, fuchsia, white and bi-coloured. Their dark, green leaves appear velvety because they have a fleshy texture and are covered with fine hairs. The plants maintain a compact form but do come in a trailing form. Lots of choices!

African violets prefer soil that has excellent drainage because the plant may rot if water lays on top or the soil stays water logged. You may purchase specific African violet soil to help ensure a porous growing medium that allows water to percolate through.
Water your plant so that the soil stays moist all of the time but pour off the standing water from the saucer under the plant to prevent the soil from becoming water logged. Do not get water on the leaves of this plant because disfiguring rings will appear where the leaf has been damaged. You may also use a system that allows you to water your African violet from the bottom. This can be as simple as filling the saucer under your plant with water then allowing the plant to absorb water from the saucer. Discard any water left in the sauce after about 45 minutes. Remember to check the surface of the soil to make sure that it is moist … if not, then repeat this process. There are also self-watering pots available. Over-watering or under-watering will damage and may eventually kill your plant.
African violets like bright indirect light. A sunny, warm window is okay in winter but in summer, place your plant in a north or east window or just sit it back from a south or west window so that it does not receive direct sunlight. African violets prefer cooler temperatures at night around18C (60F) and up to 27-29C (80-85F) in the day. Too cool temperatures will stunt their growth.
Like any houseplant, African violets can suffer from some diseases and insect pests including botrytis blight, powdery mildew, mites, mealybug, aphids or thrips. Be sure to purchase your African violet and all of your house plants from a reputable seller to avoid these problems.
With all of the new African violet cultivars and their colourful blooms, why not try one? If you enjoy house plants then the African violet may be the one for you!

This book is, without a doubt, one of my favourite go-to gardening books! The new revised third edition of Lorraine Johnson’s book, 100 Easy-to-Grow Native Plants for Canadian Gardens, is a testament to Lorraine’s expertise. She writes in the forward that “one of the greatest satisfactions of growing native plants is that you are supporting a complex web of ecological relationships that are the basis of a healthy, resilient ecosystem.” Lorraine Johnson is the former president of the North American Native Plant Society and the author of numerous other books. She lives in Toronto.
The photos by Andrew Layerle, along with detailed descriptions of the plants, make this book most helpful when trying to decide what native plants you would like to incorporate into your garden. I think many of us can relate to her point that “gardeners tend to be voyeuristic creatures and plant lists are our chaste form of porn”! We all crave the perfect plant and often browse through books over the winter months with dreams of starting a new garden and we wait patiently for the spring weather that allows us to once again get our hands dirty.
The plants are divided into a number of different categories and Lorraine does a good job at listing the common name (although she warns there are sometimes many), the botanical name, the height, blooming period, exposure, moisture, habitat and range. She gives a good description, the maintenance and requirements, along with suggestions on propagation and good companions. I love that she also mentions the wildlife benefits of each plant.
Lorraine has also included Quick-Reference Charts at the back of the book that separate the plants by region as well as specific conditions, such as acidic soil, water requirements, etc. She has lists of plants suitable to prairie habitat, drought-tolerant plants, plants for moist areas, and plants that attract butterflies and other pollinators.
