Noted for its splendid floral display in spring, Fraxinus ornus (Flowering Ash) is a pretty, medium-sized, deciduous tree with a short trunk and a dense oval to almost round, irregular crown. In late spring, fragrant, showy white flower panicles appear above the foliage. They are followed by clusters of winged seeds, 2 in. long (5 cm), that ripen in fall and may persist on the tree throughout winter. The foliage of compound pinnate, mat blue-green leaves contains 5-9 leaflets which sometimes turn rich shades of yellow-burgundy to red-purple in the fall. After dropping to the ground, the attractive smooth, silver bark is revealed, providing winter interest. Flowering Ash is a splendid shade tree or specimen tree for a large landscape.
