Fraxinus americana
''Fraxinus americana'' (white ash or American ash) is a species of ''ash tree'' native to eastern and central North America. It is found in mesophytic hardwood forests from Nova Scotia west to Minnesota, south to northern Florida, and southwest to eastern Texas. Isolated populations have also been found in western Texas, Wyoming and Colorado, and the species is reportedly naturalized in Hawaii.〔Germplasm Resources Information Network: (''Fraxinus americana'' )〕〔(Kew World Checklist of Selected Plant Families, ''Fraxinus americana'' )〕〔(Biota of North America Program, map, ''Fraxinus americana'' )〕 ==Characteristics== The name White Ash derives from the glaucous undersides of the leaves. It is similar in appearance to the Green Ash, making identification difficult. The lower sides of the leaves of White Ash are lighter in color than their upper sides, and the outer surface of the twigs of White Ash may be flaky or peeling. Green Ash leaves are similar in color on upper and lower sides, and twigs are smoother. Despite some overlap, the two species tend to grow in different locations as well; White Ash is a forest tree that commonly occurs alongside Sugar Maple while Green Ash is a pioneer species that inhabits riparian zones and disturbed areas.〔Common Trees of the North Carolina Piedmont: (''Fraxinus americana'' )〕〔New Brunswick tree and shrub: (''Fraxinus americana'' )〕
