Growing conditions
It needs full sun. USDA rates it as having moderate water needs. Its drought tolerance is rated none — it needs reliable moisture. It handles periodically wet ground (USDA rates its anaerobic tolerance medium). It is recorded on soils from pH 3.5 to 7 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 4.
Size and growth
At maturity it reaches about 9.8 ft, making it a plant that will finish above head height. It grows quickly.
Bloom period
USDA records a bloom period of June through August. Flowers are green.
A flowering date, not a pollinator rating.
Foliage, flower and season
Summer foliage is green, coarse in texture. Its flowers are not conspicuous — a plant for form and foliage. It carries conspicuous autumn colour. Its active growth period is summer. USDA rates its lifespan as moderate.
What the site needs to provide
USDA records it across sites receiving 35 to 60 inches of annual precipitation. It needs at least 110 frost-free days to finish its season. It roots to at least 24 inches. Fertility requirement: medium.
Propagating it
Sprigs is the only propagation method USDA lists. Its seed spreads at a moderate rate. It does not spread vegetatively, so it will stay where you put it.
Resilience and wildlife
Its fire tolerance is rated none. Its growth form is recorded as bunch.
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. The layer is derived by a fixed rule from growth habit and mature height.

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.
