Growing conditions

It needs full sun. USDA rates it as having moderate water needs. It is recorded on soils from pH 3.5 to 7 β€” a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 4; 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 9.8 ft, making it a mid-sized plant. It grows quickly, which matters when you are timing a planting around the layers above it.

Bloom period

USDA records a bloom period of June through August. The flower color USDA records is green. 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 β€” no dataset we trust publishes one, so we do not make that claim. See Data & sources.

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 SAGI, 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.
