Fraxinus
Also called Ashes
Ash (Fraxinus) is a genus of 45 to 65 mostly deciduous medium-to-large trees in the olive family, native across much of Europe, Asia and North America. Commonly grown members are valued as shade and street trees, and they are best given full sun and deep, moist soil.
Fraxinus (), commonly called ash, is a genus of plants in the olive and lilac family, Oleaceae, and comprises 45–65 species of usually medium-to-large trees, most of which are deciduous (dropping their leaves in autumn), although some subtropical species are evergreen. The genus is widespread throughout much of Europe, Asia, and North America.
The leaves are usually opposite, and mostly pinnately compound (divided into leaflets in a feather-like arrangement). The seeds, known as "keys", are botanically fruits of the type called samara. Some species are dioecious, having male and female flowers on separate plants.
The genus Fraxinus is widespread throughout much of Europe, Asia, and North America. The genus is primarily temperate or subtropical; 22 of the species occur in China, while for example Italy has 4 species. Both native and introduced Fraxinus species occur in almost every contiguous state of the United States and all the southern provinces of Canada.
Ash is a hardwood and is dense, around 670 kg/m3 for Fraxinus americana, the white ash, and 710 kg/m3 for Fraxinus excelsior, the European ash. The wood of the European ash is strong and elastic, making it suitable for uses such as the handles of tools. It is a good firewood.
