Lavandula dentata

French Lavender

Spreading shrub, growing 1 m tall and 1.5 m across. Linear-oblong, dark green leaves. Purple-blue flowers; can flower most of the year in milder climates (e.g. Southern Europe, California, Sth. East Queensland).

Uses

Container plant, garden shrub, hedging plant and cut flower. Particularly useful in areas where humidity can be higher.

Culture

Grows well across a wide range of climates from temperate to sub-tropical. Cut back 50% of the foliage each spring, after coldest weather has gone (some cultivars may tolerate minimum temperatures around 12 degrees Celsius; but most best kept above minus 5 Celsius). At the same time side dress soil with agricultural lime and apply a general fertilizer.
Grows and flowers better in warmer, more humid climates e.g. in sub-tropical South East Queensland, this species can flower for 9 months of the year, and live in the ground for well over a decade.

Propagation

Cuttings.
