Growing conditions

It needs full sun. USDA rates it as having needs consistently moist ground. It is recorded on soils from pH 5.5 to 7.5 โ€” a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 9; 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 1.4 ft, making it a low, mat-forming plant. It grows at a moderate rate, 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 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.

Where this data comes from

Every value on this page comes from the USDA PLANTS database record for symbol HEAL5, 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.
