Japanese ash, botanical name Fraxinus lanuginosa, is a deciduous tree species native to Japan and parts of eastern Asia. Also commonly known as the downy ash or wax ash, it belongs to the Oleaceae family of flowering plants. The tree typically reaches heights of 10 to 20 meters and often has a spreading crown with a rugged appearance.
The Japanese ash is characterized by its distinctive foliage, which consists of compound leaves composed of 5 to 11 leaflets. The leaves are ovate in shape, have serrated margins, and are covered in a soft, downy or hairy texture, hence the name "lanuginosa." During the summer, the leaves have a dark green color, turning to vibrant shades of yellow or purple in autumn.
In spring, the Japanese ash produces small, inconspicuous flowers that form in clusters, with both male and female flowers found on the same tree. Following flowering, the tree produces winged fruits known as samaras, which ripen and are dispersed by wind.
As an ornamental tree, Japanese ash is often planted for its attractive foliage and unique bark texture. It thrives in a variety of soil types and tolerates a range of environmental conditions, making it suitable for urban landscapes, parks, and gardens. It also provides light shade and is valued for its ability to attract birds and other wildlife.
In addition to its aesthetic qualities, Japanese ash wood is highly regarded for its durability and strength. It is commonly used in furniture making, flooring, and construction, as well as for the production of traditional Japanese tools and utensils.
