The staminate flowers of the red ash are afflicted by mites in the same way as those of the white ash, producing unsightly clusters which hang on the tree all winter.
The wood is much less valuable than that of the white ash.
Black Ash Fraxinus nigra
A slender tree, 40 to 70 feet high. Trunk dark gray, often disfigured with knobs. The buds are black, and the young shoots greenish. Coarse twigs; opposite leaf-scars.
The black ash is distinguished from the white and red ashes by its darker buds and by having a less pinched, flattened appearance at the nodes on the stem. It grows throughout New England in swamps, in wet woods, and in moist, muddy ground near rivers. In the woods its trunk is found frequently without branches to a great height, and Emerson calls it the most slender deciduous tree to be found in the forest. It is sometimes seventy or eighty feet high, with a trunk scarcely a foot in diameter.
The wood of the black ash is heavy but not strong. It is used for fences, for the interior finish of houses, and, after being separated into thin strips, it is used in making baskets and the bottoms of chairs. Its sap was an old remedy for earache, obtained by holding a green branch before the fire.
The specific name, nigra, refers to the color of the buds.
European Ash Fraxinus excelsior
A large tree, with a lofty, spreading head and short, thick trunk. The bark is ash-colored when old, and dark gray when young. Very black buds distinguish it from the American species. Opposite leaf-scars.
The European ash is planted frequently along roadsides and in our parks and gardens. It is indigenous to Northern, Central, and Southern Europe. Its jet black buds distinguish it from other ash trees. In the chapter called “A Visit to an old Bachelor,” in Mrs. Gaskell’s “Cranford,” Mary Smith tells us how she was talking to Mr. Holbrook in the fields, and how he quoted poetry to himself and enjoyed the trees and clouds and glimpses of distant pastures, and how he suddenly turned sharp round and asked, “Now, what color are ash buds in March?”
