Growing conditions
It grows in partial shade. USDA rates it as having low water needs once established. It is recorded on soils from pH 5.9 to 7 — 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 18 ft, making it a mid-sized plant. It grows slowly, which matters when you are timing a planting around the layers above it.
Bloom period
USDA records a bloom period of February. The flower color USDA records is white. 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 — no dataset we trust publishes one, so we do not make that claim. See Data & sources.
Role in a guild
Shrub layer. In a layered planting this is woody mid-level structure between the understory and the ground. 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 ARGL4, 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.
