Growing conditions
It is recorded on soils from pH 5 to 8 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 11.
Size and growth
At maturity it reaches about 2 ft, making it about knee height.
Foliage, flower and season
Summer foliage is green. Its flowers are conspicuous. 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
USDA records it across sites receiving 30 to 80 inches of annual precipitation. It needs at least 365 frost-free days to finish its season. It roots to at least 12 inches. Fertility requirement: 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.
