Growing conditions
It needs full sun. It is recorded on soils from pH 4.5 to 7.3 — a broad range that spans acidic through mildly alkaline ground.
Size and growth
At maturity it reaches about 2 ft, making it a low to knee-height plant.
Role in a guild
Ground cover. In a layered planting this is the lowest layer — 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.
