Genus

Lavandula

The Lavandula genus in the Plotwright catalog — 2 species: English lavender, French lavender. Open any for hardiness, native range, wildlife value, and growing guidance.
Lavandula angustifolia
English lavender
A Mediterranean-native evergreen subshrub for sunny edges, pollinator beds, and low-water garden structure. The source of true oil of lavender; well-loved but at times difficult to grow east of the Mississippi because it does not tolerate wet feet or heavy clay.

Structure
Lavandula stoechas
French lavender
A compact, evergreen, aromatic subshrub from the Mediterranean basin, 18-36 inches tall and wide, with narrow grey-green leaves and dense, dark-purple flower spikes that are each topped by a showy tuft of violet bracts — the unmistakable "rabbit ears" that distinguish French lavender from English lavender. It loves heat, full sun, and sharp drainage, blooms long and early, and is one of the best bee and butterfly nectar plants you can grow on a hot, dry site. Be clear-eyed about its limits, though: it is less cold-hardy than English lavender (Lavandula angustifolia), it is short-lived on heavy or wet soil, and it self-seeds readily — it is recorded as invasive in parts of Australia and other Mediterranean-climate regions, so deadhead it and site it responsibly outside its native range. It is intensely aromatic but is NOT the culinary lavender, and it is grown as an ornamental rather than for food.
