Growing conditions
It grows in partial shade. USDA rates it as having moderate water needs. Its drought tolerance is rated low. It handles periodically wet ground (USDA rates its anaerobic tolerance medium). It is recorded on soils from pH 4.8 to 6.4 — acidic ground. Its cold limit is zone 2.
Size and growth
At maturity it reaches about 0.4 ft, making it a low, mat-forming plant. It grows at a moderate rate.
Bloom period
USDA records a bloom period of July. Flowers are green.
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 summer and fall. USDA rates its lifespan as long.
What the site needs to provide
USDA records it across sites receiving 36 to 55 inches of annual precipitation. It needs at least 80 frost-free days to finish its season. It roots to at least 6 inches. Fertility requirement: low — no feeding needed on ordinary garden soil.
Propagating it
Propagate it from seed, bare root and sprigs. USDA records no cold-stratification requirement, so seed should germinate without a chilling period. Its seed spreads at a slow rate. It spreads vegetatively at a moderate rate.
Resilience and wildlife
Browsing animals rate it barely palatable — the sourced basis for calling it deer-resistant. Its fire tolerance is rated high. Its growth form is recorded as stoloniferous.
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.

Where this data comes from
Every value on this page comes from the USDA PLANTS database record for symbol CABI5, or is computed from those values by a fixed rule. Nothing here is estimated or model-generated. Where USDA publishes no value, this page omits the claim rather than filling the gap.
