Growing conditions
It tolerates full shade. USDA rates it as having needs consistently moist ground. Its drought tolerance is rated low. It tolerates saturated, poorly drained ground well (USDA rates its anaerobic tolerance high). It is recorded on soils from pH 4.5 to 6.3 — acidic ground. Its cold limit is zone 6.
Size and growth
At maturity it reaches about 65 ft, making it a large tree that will dominate its site. It grows slowly.
Bloom period
USDA records a bloom period of June. Flowers are white.
A flowering date, not a pollinator rating.
Foliage, flower and season
Summer foliage is dark green, coarse in texture. Its flowers are conspicuous. Its active growth period is spring, summer, fall. Its winter foliage is dense, which makes it useful for year-round screening. USDA rates its lifespan as moderate.
What the site needs to provide
USDA records it across sites receiving 44 to 70 inches of annual precipitation. It needs at least 230 frost-free days to finish its season. It roots to at least 20 inches. Fertility requirement: medium.
Propagating it
It takes readily from seed, cuttings, bare root and container stock. USDA records no cold-stratification requirement, so seed should germinate without a chilling period. 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 highly palatable, so expect deer and rabbits to take an interest. Its fire tolerance is rated low, 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.

Where this data comes from
Every value on this page comes from the USDA PLANTS database record for symbol GOLA, 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.
