Wood ash from a campfire. Wood ash is the powdery residue remaining after the combustion of wood, such as burning wood in a fireplace, bonfire, or an industrial power plant.It is largely composed of calcium compounds, along with other non-combustible trace elements present in the wood, and has been used for many purposes throughout history.
Fraxinus anomala is a deciduous shrub or small tree approaching maximum heights of five to six meters. The leaf may be simple or it may be compound, composed of up to five leaflets which look like individual leaves. Each leaflet is oval-shaped to round and may have teeth along the edges. The undistinguished brownish flowers lack petals.
[4] [5] The white ash's compound leaves usually have seven leaflets per leaf whereas the counts in other ash trees more often vary. [6] Like other species in the section Melioides, Fraxinus americana is dioecious, with male and female flowers produced on separate individuals. [7] The C-shaped leaf scars of white ash are useful in distinguishing ...
European ash in flower Narrow-leafed ash (Fraxinus angustifolia) shoot with leaves. Fraxinus (/ ˈ f r æ k s ɪ n ə s /), commonly called ash, is a genus of plants in the olive and lilac family, Oleaceae, [4] and comprises 45–65 species of usually medium-to-large trees, most of which are deciduous trees, although some subtropical species are evergreen trees.
Bark and leaf. It is the most widely distributed of all the American ashes; its range centers on the midwestern U.S. and Great Plains. Seedlings of the tree have a high tolerance to water logging [12] which may explain why the natural habitat of green ash is almost exclusively stream sides and bottomlands.
Birds, like wood ducks, feed on the fruit of a Fraxinus profunda. [4] Deer feed on the twigs and leaves of the pumpkin ash tree, and the humans use the woody parts of the tree as lumber for building. [4] In addition to being used as lumber, the wood of pumpkin ash trees can also be used in tools such as stocks or handles. [14]
The leaves are 13–21 cm long, pinnately compound with usually five rounded leaflets 3–7.5 cm long and 2–5 cm broad. The flowers are purple, produced in small clusters in early spring; like all ashes, the Texas ash is dioecious, with male and female flowers on separate trees.
The leaves are 25–40 cm long, pinnate compound, with 7–13 leaflets, the leaflets 5–20 cm long and 2–5 cm broad, subsessile on the leaf rachis, and with a serrated margin. They turn to a golden-yellow in early autumn, and the tree is usually early to change color.
