About Norway Maple

Acer platanoides · also called Norway Maple, Plane Maple · flowering

Norway Maple is a large, fast-growing deciduous tree native to Europe and western Asia, valued for its dense round canopy, bright yellow-green flowers in spring before leaf emergence, and vivid yellow autumn colour. Extremely hardy and pollution-tolerant, it is widely planted as a street and park tree. ASPCA lists maples as potentially toxic to horses.

Cold limit: USDA 3-7 · RHS H7 (-30–25°C)

What norway maple's hardiness rating actually means

Yes — norway maple is genuinely cold hardy. Rated RHS H7 and USDA 3-7, it lives outdoors all year and needs winter cold rather than protection from it. Its RHS rating of H7 means: Hardy in the severest European continental winters. On the US scale that maps to USDA 3-7 — the zones where it can be left outdoors year-round.

New to these scales? The USDA hardiness zone map explained covers how the zone numbers work, and you can find your own zone with the zone finder.

Minimum temperature — and what happens below it

Minimum survivable temperature is roughly below about −20 °C. Norway Maple is built for winter — once established it takes hard frost and snow in its stride.

Concretely, for norway maple as it gets too cold:

It tolerates winter lows to about −20 °C once established.
Below its rated zone, the visible damage is browned or blackened top growth and, in the worst case, a killed crown or root.
First-year, newly planted, or container-grown specimens are noticeably less hardy than established garden plants — the roots are exposed.

Can norway maple go outside or overwinter — and where?

Plant it out within USDA 3-7 and it overwinters with little or no help.
It does not want to come indoors — a warm winter room actually weakens a hardy plant by denying it dormancy.
The real risks in its range are waterlogging, wind-rock on young plants, and a late hard frost on new growth — not ordinary winter cold.

Work back from your local frost dates with the frost-date calculator: the last spring frost and first autumn frost are what really decide when norway maple can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H7 figure above.
