Growing conditions

Its drought tolerance is rated none — it needs reliable moisture. It handles periodically wet ground (USDA rates its anaerobic tolerance medium). Its cold limit is zone 11.

Size and growth

At maturity it reaches about 20 ft, making it a small tree or large shrub.

Bloom period

USDA records a bloom period of June through August. Flowers are purple.

A flowering date, not a pollinator rating.

Foliage, flower and season

Summer foliage is green, medium in texture. Its flowers are not conspicuous — a plant for form and foliage. Its active growth period is year round. USDA rates its lifespan as short, so plan on replacing or resowing it rather than treating it as permanent structure.

What the site needs to provide

It needs at least 120 frost-free days to finish its season. It roots to at least 12 inches. Fertility requirement: low — no feeding needed on ordinary garden soil.

Propagating it

Propagate it from seed and cuttings. USDA records no cold-stratification requirement, so seed should germinate without a chilling period. Its seed spreads at a rapid rate.

Resilience and wildlife

Browsing animals find it highly palatable, so expect deer and rabbits to take an interest. Its fire tolerance is rated medium.

Role in a guild

Shrub layer. In a layered planting this is woody mid-level structure between the understory and the ground. The layer is derived by a fixed rule from growth habit and mature height.
