Family

Oleaceae

Botanical Name

FRAXINUS 'Fan-West'

Plant Common Name

Ash, Fan-West Ash

General Description

The vigorous, sterile ash, ‘Fan-West’, is super tough. It thrives in poor, dry soils and also grows well in cold, windy, harsh locations. This outstanding deciduous shade tree has a strong upright central leader and broad, rounded crown with great branching. It is a hybrid between two North American natives, the velvet ash (Fraxinus velutina) and the green ash (F. pennsylvanica) that was discovered by Eddie Fanick of San Antonio,Texas as a natural seedling on the banks of the Guadalupe River.

Throughout the growing season ‘Fan-West’ has attractive compound leaves with five to seven leaflets that are light olive green. These have opposite arrangement and turn yellow in autumn. Most ashes flower early in the season, but this cultivar is sterile and therefore fruitless too.

Ashes grow best in locations with full to partial sun. In the wild, they commonly grow in lowlands, so they will tolerate some soil moisture and will withstand a wide range of soil conditions. They are classic large shade tree for open areas and street sides and are highly tolerant of salt and urban conditions. Avoid planting ashes where the emerald ash borer has become a problem.
