Green Ash


(Fraxinus pennsylvanica subsp. null)

Native to southern Ontario and eastern North America and the most adaptable of all the ashes. The Green Ash can grow in a wide range of conditions and soils, though it prefers moist environments. Small to medium sized trees, widely planted residentially and frequently used for furniture. Smaller branches form a slight "S" shape as they droop towards the ground, then curve upwards at the tips. Green Ash numbers have been reduced dramatically due the the Emerald Ash Borer.


5-9 (usually 7) oblong-lanceolate leaflets. Yellowish-green in colour and paler on the underside. In the spring, foliage appears before flowers (unlike the White Ash). In autumn, leaves take on a nice yellow-brown colour.

Seeds & Fruit

Light green (then tan) samara appear in clusters of large amounts. Ash samara are an important food for wildlife including rabbits and birds. Seeds may be dormant for a few years on the ground before germinating.

Twigs & Buds

Greyish-brown, somewhat stout twigs with reddish-brown hairy buds. Buds appear above the leaf scar forming somewhat of a half-circle shaped leaf scar (U-shaped for the White Ash). The top pair of lateral buds are close to the terminal bud
