Growing conditions

It grows in partial shade. USDA rates it as having moderate water needs. Its drought tolerance is rated medium. It will not tolerate waterlogged soil — USDA rates its anaerobic tolerance as none. It is recorded on soils from pH 5.6 to 8 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 4.

Size and growth

At maturity it reaches about 229 ft, making it a large tree that will dominate its site. It grows quickly.

Bloom period

USDA records a bloom period of March through May. Flowers are brown.

A flowering date, not a pollinator rating.

Foliage, flower and season

Summer foliage is green, fine in texture. Its flowers are not conspicuous — a plant for form and foliage. Its fruit or seed heads are conspicuous, extending interest past flowering. Its active growth period is spring, summer, fall. USDA rates its lifespan as long.

What the site needs to provide

USDA records it across sites receiving 25 to 90 inches of annual precipitation. It needs at least 150 frost-free days to finish its season. It roots to at least 40 inches, too deep for containers or thin soil over bedrock. Fertility requirement: low — no feeding needed on ordinary garden soil.

Propagating it

It takes readily from seed, cuttings, bare root and container stock. Seed needs cold stratification — a period of moist chilling — before it will germinate, so sow in autumn or chill it artificially before a spring sowing. Its seed spreads at a slow rate. It does not spread vegetatively, so it will stay where you put it.

Resilience and wildlife

Browsing animals find it moderately palatable, so expect deer and rabbits to take an interest. Its fire tolerance is rated low. Its growth form is recorded as single stem.

Role in a guild

Canopy. In a layered planting this is the tallest layer of a planting — it sets the light budget everything beneath it lives on. 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 PILA, 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.
