Glorious Lilies

by Christine Freeburn, Master Gardener

One of the most spectacular blooming flowers in the garden are from the genus Lilium. The large 6-petalled trumpet flowers stand on upright herbaceous stems. The fragrance emitted from some can perfume the entire neighbourhood. Lilies form from bulbs that have scaly layers and depending on the variety can bloom in your garden for a short period from June or into the summer months.

There are hundreds of species and varieties, and more being hybridized each year. There are basically 9 different types described by the North American Lily Society. They include hybrids like Asiatic, Oriental, Longiflorum, Trumpet, Martagon, Candidum, American and Interdivisional as well as Species. Most are perennial in our zone, some are fragrant.

Lilies prefer full sun and need well drained soil to grow well. Lilies are toxic to cats. Many lilies from the Asiatic, Oriental, Trumpet and Martagon families are susceptible to attack from Asian Lily Beetle.

For more information about lilies you might want to add to your garden Ontario Regional Lily Society and North American Lily Society
