What
are Ash Trees ? Ash trees are any member of Genus Fraxinus,
comprising about 70 species of mostly northern temperate trees and
shrubs, valued for timber and ornament. Characteristic of the group
are the small, inconspicuous greenish flowers, usually borne in clusters
with or without sepals and petals. These appear in early spring and
produce dry, single-winged fruits called samaras.

about ash trees : The finely toothed leaves are opposite
on the stems and are compound, bearing an odd number of leaflets.
The white, or American, ash, European ash, and Siebold ash of Asia
are particularly valuable sources of woods used in cabinetry. The
flowering, or manna, ash, notable for its long petals, is cultivated
in Mediterranean regions for its sweet gum.
In North
America, ashes have been subject for several years to a disease that
usually kills a stricken tree in ten years. No preventative has yet
been found for the disease, which may possibly be caused by a leafhopper-borne
mycoplasma.
