Growing conditions

It needs full sun. USDA rates it as having low water needs once established. 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 4.6 to 6.5 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 11.

Size and growth

At maturity it reaches about 1.4 ft, making it a low, mat-forming plant. It grows quickly.

Bloom period

USDA records a bloom period of July. Flowers are white.

A flowering date, not a pollinator rating.

Foliage, flower and season

Summer foliage is green, coarse in texture. Its flowers are conspicuous. Its active growth period is summer.

What the site needs to provide

USDA records it across sites receiving 35 to 55 inches of annual precipitation. It needs at least 155 frost-free days to finish its season. It roots to at least 8 inches. Fertility requirement: low — no feeding needed on ordinary garden soil.

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 slow rate. It does not spread vegetatively, so it will stay where you put it.

Resilience and wildlife

Browsing animals find it moderately 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.
