A group of 25 woody perennial shrubs, mostly native to dry, sunny sites found along the Mediterranean.
Lavenders grow best in fast-draining soil and in full sun.
Good air circulation is necessary to deter fungal diseases. Prune plants lightly in early spring to shape, and after flowering to divert energy into foliar growth rather than seed production. Lavenders can be propagated by seed, or to ensure lineage, by semi-ripe cuttings. Lavenders may develop root rot and fungal diseases when grown in wet areas. Mildew is a problem in humid areas.
