In mid to late spring, the tree produces small flowers that are not very noticeable. It is dioecious; it requires two separate plants (male and female) to successfully pollinate and reproduce. The fruit, produced by female trees, is a cluster of samaras, 3–5 cm (1 + 1 ⁄ 8 –2 in) long that includes wings similar to maple trees. It is ...
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.
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 fruit is a samara 1.5–3 cm long, with an apical wing. It is long-lived and drought tolerant. [4]
Fraxinus angustifolia subsp. angustifolia has become a weed in many parts of Australia, where it is known as Desert Ash. It has been widely planted as a street and park tree, and has spread to native bushland and grasslands, as well as stream banks and drainage lines, out-competing native plants for moisture, light and nutrients.
Green’s mountain ash (S. scopulina) is native to the mountains from Alaska to California, and east to the Rocky Mountains and Northern Great Plains. It grows as a multi-stemmed shrub that is ...
Male flowers Seeds of Fraxinus excelsior, popularly known as "keys" or "helicopter seeds", are a type of fruit known as a samara. It is a large deciduous tree growing to 12–18 m (39–59 ft) (exceptionally to 43 m or 141 ft) tall with a trunk up to 2 m (6.6 ft) (exceptionally to 3.5 m or 11 ft) diameter, with a tall, narrow crown.

However, unlike that species, Fraxinus mandshurica is dioecious, with male and female flowers produced on separate individuals. [2] The spelling of the species name is disputed; some (e.g. the Flora of China [1]) cite mandschurica, while others (e.g. USDA GRIN [3]) cite mandshurica. The original 1857 Russian publication spelled it without the ...
