Commonly called French lavender, this species is actually cultivated more as an ornamental, flowering shrub. Foliage and flowers are strongly lavender with a hint of rosemary, but the flavor is inappropriate for cooking. Also, flowers do not dry well, so generally are not cut for ornamental value. The species has been in cultivation for nearly a thousand years, traced back to its use in bathing by the Arabs.
Leaves are a medium green and toothed, giving the plant a feathery look. If planted in a frost free area or protected, French lavender will grow and bloom year round. It can survive some hard freezes, however will show severe damage and will need to be pruned back after the last frost date.
Flower spikes are rounded, light mauve-lavender flowers and green buds.
Prune back occasionally to promote new growth and flowers. If pruned more severely early in the season, the plant will stay more compact – otherwise over time it will have a tendency to open up and sprawl.
