Growing conditions

It needs full sun. USDA rates it as having moderate water needs. Its drought tolerance is rated high. It will not tolerate waterlogged soil — USDA rates its anaerobic tolerance as none. It is recorded on soils from pH 5.6 to 7.6 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 8.

Size and growth

At maturity it reaches about 0.8 ft, making it a low, mat-forming plant. It grows quickly.

Bloom period

USDA records a bloom period of March through April. Flowers are purple.

A flowering date, not a pollinator rating.

Foliage, flower and season

Summer foliage is green, fine in texture. Its flowers are conspicuous. It carries conspicuous autumn colour. Its fruit or seed heads are conspicuous, extending interest past flowering. Its active growth period is fall, winter and spring.

What the site needs to provide

USDA records it across sites receiving 12 to 24 inches of annual precipitation. The low end of that band is genuinely arid, so it has a wide tolerance for dry country. It needs at least 240 frost-free days to finish its season. It roots to at least 12 inches. Fertility requirement: medium.

Propagating it

Seed is the only propagation method USDA lists. Division and cuttings are not listed as options. USDA records no cold-stratification requirement, so seed should germinate without a chilling period. Its seed spreads at a rapid rate. It does not spread vegetatively, so it will stay where you put it.

Resilience and wildlife

Browsing animals find it highly palatable, so expect deer and rabbits to take an interest. Its fire tolerance is rated none. Its growth form is recorded as single crown.

Role in a guild

Ground cover. In a layered planting this is the lowest layer — it shades soil, holds moisture, and suppresses weeds. The layer is derived by a fixed rule from growth habit and mature height.
