Lavender is difficult to grow from seed because the seed is slow and erratic—there is a poor germination percentage even under ideal greenhouse conditions. Most Lavender is propagated vegetatively, so start with young plants purchased from a garden centre.
How Much: At least two plants.
When: Early spring; can withstand a light frost.
Where: Full sun. Demands dry, sandy, very well-drained soil. Space plants 30 to 45 cm apart.
Care and Nurture
Lavender requires some care to grow well. Although commercial plantings of lavender can last up to 30 years, most of us are best off replacing our lavender plants about every 3 years: they tend to get tough and woody. Prune lightly in the spring to shape and remove any winter-killed growth. Never cut into old wood: it sets the plant back. Never prune when frost is imminent: a tender perennial, lavender is easily damaged and needs protection from cold. Heavy foliage in the fall helps to trap the snow for insulation.
Harvest leaves and flowers as needed throughout the season. Lavender leaves and flowers are not only edible, but can also be used in a variety of handcrafts and products for the home.
For best flavour: Harvest leaves just before the last flowers on each stalk have opened fully.
Leaves: Cut sprigs where they attach to the main growing stem; use whole or strip the leaves from the top down. Discard tough stems.
Flowers: Clip individual flowers from stems. Remove all green or brown bits from the flowers before eating.
Preserving the Harvest
Use flowers fresh, dried, or frozen; freeze fresh flowers as soon as you harvest them. Use leaves fresh or dried.

- I've grown lavender on the north side of my house for five years and it has done well, although the flowers are smaller than average.
- Flies and mosquitoes do not like the scent of lavender. A sachet made from oil of lavender on a cotton ball tied and hung in a room is said to keep the room free of flies. However, lavender is very attractive to butterflies, moths, and bees, and provides a good source of nectar.
