Growing conditions
It needs full sun. USDA rates it as having moderate water needs. It is recorded on soils from pH 6.8 to 7.5 — 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 12 ft, making it a mid-sized plant. It grows quickly, which matters when you are timing a planting around the layers above it.
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.
