Growing conditions

It tolerates full shade. USDA rates it as having moderate water needs. It is recorded on soils from pH 6.4 to 7.4 โ€” a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 10; 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 4.9 ft, making it a low to knee-height plant. It grows quickly, which matters when you are timing a planting around the layers above it.

Role in a guild

Understory. In a layered planting this is the layer beneath the canopy, tall enough to hold structure but shaded from above. 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 IMCA, 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.
