The red ash grows up to 83 feet high (25 metres) and has an estimated life span of about 100 years. It is widely distributed in the eastern United States, and in Canada ranges from central Saskatchewan to eastern central Quebec.
The red ash leaf consists of 5 to 9 leaflets.
Its key-like fruit, consisting of one long wing, occurs in bunches. They remain on the branches in winter. And visitors, such as the black-headed grosbeak, feed on the fruit throughout the cold season.
Red ash grows quickly, but rarely in forests, since it thrives best in open areas such as plains.
Even in the open areas, it occurs mixed with willow, eastern cottonwood and silver maple.
Its wood is heavy, hard and weak. It is used in the same way as the white ash, but much less frequently.
Because of its smaller size, it is an excellent ornamental in cities.
Leaves, in opposite pairs, consisting of 5 to 9 leaflets with rounded teeth from the centre to the tip of the leaflet.
Fruits, long key, in clusters, on stalks.
