Growing conditions
It tolerates full shade. USDA rates it as having moderate water needs. Its drought tolerance is rated none — it needs reliable moisture. It handles periodically wet ground (USDA rates its anaerobic tolerance medium). It is recorded on soils from pH 4.4 to 6 — acidic ground. Its cold limit is zone 3.
Size and growth
At maturity it reaches about 0.9 ft, making it a low, mat-forming plant. It grows at a moderate rate.
Foliage, flower and season
Summer foliage is green, fine in texture. Its flowers are not conspicuous — a plant for form and foliage. Its active growth period is spring. USDA rates its lifespan as moderate.
What the site needs to provide
USDA records it across sites receiving 32 to 60 inches of annual precipitation. It needs at least 90 frost-free days to finish its season. It roots to at least 10 inches. Fertility requirement: medium.
Propagating it
Propagate it from bare root and sprigs. It spreads vegetatively at a slow rate.
Resilience and wildlife
Its fire tolerance is rated high. Its growth form is recorded as rhizomatous.
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.
