Norway maple
Acer platanoides · Aceraceae
Norway maple (Acer platanoides) is a perennial tree in the Aceraceae family. It is introduced to North America rather than native. USDA records it as hardy in zone 3 and warmer, down to about -33°F.
⚠ Invasive or noxious status. USDA lists this plant with an invasive or noxious weed status somewhere in its range. Check your state's noxious weed list before planting it — in some states it is illegal to sell or plant.

Growing conditions
It grows in partial shade. USDA rates it as having moderate water needs. Its drought tolerance is rated low. It will not tolerate waterlogged soil — USDA rates its anaerobic tolerance as none. It is recorded on soils from pH 4.8 to 7.2 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 3.
Size and growth
At maturity it reaches about 50 ft, making it a substantial woody plant. It grows slowly.
Bloom period
USDA records a bloom period of April through May. Flowers are green.
A flowering date, not a pollinator rating.
Foliage, flower and season
Summer foliage is red, medium in texture. Its flowers are not conspicuous — a plant for form and foliage. It carries conspicuous autumn colour. Its fruit or seed heads are conspicuous, extending interest past flowering. Its active growth period is spring and summer. USDA rates its lifespan as moderate.
What the site needs to provide
USDA records it across sites receiving 32 to 60 inches of annual precipitation. It needs at least 130 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: medium.
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 rate it barely palatable — the sourced basis for calling it deer-resistant. 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 ACPL, 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.
