Mature specimen can attain a height of 20 - 25 m, in nature up to 40 m. The bark is grey to grey brown and deeper furrowed than F. excelsior. The leaves are odd-pinnate and have 3 - 4 pairs. They are dark green with a whitish green underside, grow to 40 cm and turn violet yellow in autumn. F. americana is dioecious and has a purple green inflorescence in April. The female flowers are followed by 2 - 5 cm long keys. Applicable as a park and avenue tree or as a solitary. In the case of avenue tree, the male trees are to be preferred, they do not bear fruits. Fraxinus americana's natural habitat is along the river banks and on the low hillsides of eastern North America. Its autumn colour is its most important ornamental characteristic.
Our trees can only be planted when they don't have any leaves. Due to the this we will start delivering again from November 2024.
