Growing conditions
It grows in partial shade. USDA rates it as having low water needs once established. It is recorded on soils from pH 7 to 8.5 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 7; 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 0.5 ft, making it a low, mat-forming plant. It grows slowly, which matters when you are timing a planting around the layers above it.
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.

Where this data comes from
Every value on this page comes from the USDA PLANTS database record for symbol ATSE, 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.
