Lilium canadense, Canada Lily. Canada lilies are hardy to at least New England or USDA zone 4. Some populations range into Canada. Heat tolerance is also good, with the native range extending into Florida and Alabama. Bright light, with some shade, is best for garden performance. Like many lilies, this species should be transplanted in the fall after the top growth has died down. While tolerant of wetter soils, very soggy soil should be avoided. Sand is a good additive at rates up to 60% sand to 40% woodland or loamy soil. Leaf humus is also appreciated. The bulbs should be planted about 6-8 inches deep.
Water well after transplanting and during the growing season if the soil gets very dry. Weak fertilizers, such as Miracle Gro can improve growth and flower production. Generally, a strength of 1/2 that recommended for house plants is sufficient, once or twice during the growing season. In very loose soil, it may be advantageous to stake the tall stalks, especially as flower buds form and the plants get more top heavy. Seed normally needs a warm, then cold period to germinate. The easiest way to plant seed is to sow it outdoors, immediately when the capsule opens and seed is released. Sow seed about 1/2 inch deep and expect germination the following year. Seed germination decreases if the seed gets very dry for long. Bulb scales can also be used to propagate this wildflower.
