Green Ash

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.

Green Ash leaves


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
