EspañolGREEN ASH
(Redirected from Fraxinus pennsylvanica)
'''Fraxinus pennsylvanica''' ('Green ash', 'red ash', 'swamp ash' or 'water ash') is a species of ash native to eastern and central North America, from central Saskatchewan and southern Quebec south to eastern Texas and northern Florida; also the western U.S. states of Montana, Utah, and New Mexico, eastward. It is the most widely distributed of all the American ashes. Naturally a moist bottom land or stream bank tree, it is hardy to climatic extremes and has been widely planted in the Plains States and Canada. The commercial supply is mostly in the South. Green ash is similar in property to white ash and they are marketed together as white ash. The large seed crops provide food to many kinds of wildlife. Due to its good form and resistance to insects and disease, it is a very popular ornamental tree.
It is a medium-sized deciduous tree reaching 15-25 m (45-75 ft.) tall with a trunk up to 50 cm in diameter. The tree's autumn color is an attractive golden-yellow, and the tree is usually the earliest to change color, sometimes being in autumn color as early as Labor Day. The flowers are produced in spring at the same time as the new leaves, in compact panicles; they are inconspicuous with no petals, and are wind-pollinated. The fruit is a samara comprising a single seed 1.5-2 cm long with an elongated apical wing 2-3 cm long and 5-7 mm broad.
It is sometimes divided into two varieties (Red Ash and Green Ash) on the basis of the narrower leaflets of the latter, but the two intergrade completely, and the distinction is no longer upheld by most botanists.
It is seriously threatened in some areas, particularly Michigan, by the emerald ash borer, a beetle introduced accidentally from Asia.
Green Ash is one of the most widely planted ornamental trees throughout the United States and much of Canada, including in western areas where it is not native. 40% of boulevard trees in Edmonton, Alberta are Green Ash.[1] It has several drawbacks as an urban tree, notably a relatively short lifespan compared to many trees (rarely over 100 years, often only 30-50 years), and (recently) the threat from the emerald ash borer. Advantages include its tolerance of urban conditions, ease of propagation, and (in eastern North America) its value for wildlife as a native species.
It was also used by Gibson to make some of their guitar, such as Gibson SG and Gibson Les Paul Studio
