Fraxinus excelsior seed

Common Ash is a broad, spreading, deciduous tree, capable of reaching 100 feet or more in height but most often seen growing at a moderate pace at 70 to 80 feet with a 60 to 90-foot spread.
The dark green, multi-divided leaves are 10 to 12 inches long and usually drop off in autumn while still green.
The inconspicuous springtime flowers are followed by clusters of 1.5-inch-long, winged fruits which turn brown and remain on the trees well after the leaves have fallen.
The low-branched, rounded silhouette of naked branches on top of the short trunk and the black, dormant leaf buds help to make common Ash an attractive winter landscape element.
