Growing conditions
It needs full sun. USDA rates it as having moderate water needs. It is recorded on soils from pH 4.5 to 7 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 5; 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 at a moderate rate, which matters when you are timing a planting around the layers above it.
Role in a guild
Nutrient layer. In a layered planting this is it contributes to soil fertility rather than to structure. 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.
