Lavender

Lavandula angustifolia (Lamiaceae) is a compact evergreen shrub native to the western Mediterranean. It grows slowly to about 4 feet tall, forming a dense mound of narrow, aromatic gray-green foliage. Spikes of lavender to purple flowers appear from June through August on slender stems held above the foliage, attracting butterflies and other pollinators.

English lavender thrives in full sun and well-drained soil across a remarkably wide pH range (4.5 to 8.5). It tolerates moderate drought once established but resents wet feet, especially in winter. Good air circulation helps prevent foliar disease. Cultivars include 'Hidcote' (compact, deep purple), 'Munstead' (early blooming, traditional), 'Grosso' (large flower spikes, high oil content), and 'Hidcote Blue'. The flowers, foliage, and essential oil have culinary, medicinal, and aromatic uses. Hardy in Zones 5a to 8b.
