Growing conditions

It is recorded on soils from pH 7.5 to 7.9 β€” alkaline ground. Its cold limit is zone 11; 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 50 ft, making it a substantial woody plant.

Bloom period

USDA records a bloom period of March through May. The flower color USDA records is yellow. 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

Canopy. In a layered planting this is the tallest layer of a planting β€” it sets the light budget everything beneath it lives on. 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 STMO, 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.
