Growing conditions
It needs full sun. USDA rates it as having needs consistently moist ground. It is recorded on soils from pH 5.7 to 8.8 โ a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 8; USDA publishes no warm-end limit, so gardeners in warmer zones should check local heat tolerance separately.
Size and growth
At maturity it reaches about 2.6 ft, making it a low to knee-height plant. It grows at a moderate rate, which matters when you are timing a planting around the layers above it.
Bloom period
USDA records a bloom period of July. The flower color USDA records is green. Bloom timing is how the Guild Builder overlaps flowering across a planting so something is in flower for as much of the season as possible.
Bloom period is a claim about when this plant flowers. It is deliberately not a pollinator rating โ no dataset we trust publishes one, so we do not make that claim. See Data & sources.
Role in a guild
Ground cover. In a layered planting this is the lowest layer โ it shades soil, holds moisture, and suppresses weeds. We derive the layer from the plant's growth habit and mature height using a fixed rule, so the same inputs always produce the same layer.
