Growing conditions

It needs full sun. USDA rates it as having low water needs once established. Its drought tolerance is rated high. It is recorded on soils from pH 4 to 7.5 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 8.

Size and growth

At maturity it reaches about 60 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 green.

A flowering date, not a pollinator rating.

Foliage, flower and season

Summer foliage is green, medium in texture. Its flowers are not conspicuous — a plant for form and foliage. It carries conspicuous autumn colour. Its active growth period is year round. Its winter foliage is dense, which makes it useful for year-round screening. USDA rates its lifespan as long.

What the site needs to provide

USDA records it across sites receiving 30 to 100 inches of annual precipitation. It needs at least 365 frost-free days to finish its season. It roots to at least 60 inches, too deep for containers or thin soil over bedrock. Fertility requirement: low — no feeding needed on ordinary garden soil.

Propagating it

Propagate it from seed and container stock. USDA records no cold-stratification requirement, so seed should germinate without a chilling period. 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, and it can resprout after damage. 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.
