White Ash

Scientific Name: Fraxinus americana

Plant Family: Oleaceae

Native Region: Eastern and central North America, from Nova Scotia west to Minnesota and south to northern Florida and eastern Texas.

White Ash

Brief Description

A large deciduous tree known for its compound leaves with 5-9 leaflets and its distinctive 'diamond' patterned bark on mature specimens. It is a major component of northern hardwood forests.

Care Instructions

Requires full sun and moist, well-draining soil. It is relatively low maintenance once established but is currently highly susceptible to the Emerald Ash Borer beetle in many regions.

Medicinal Value

We do not currently provide medicinal value for plant identifications.

Sunlight

Full sun (at least 6 hours of direct sunlight per day).

Watering

Moderate watering needs. Prefers consistently moist soil but can tolerate occasional drought once mature. Young trees need weekly watering during dry spells.

Soil

Deep, fertile, well-drained loamy soils are preferred. Tolerates a range of pH from 5.0 to 7.5.

Hardiness Zone

3 to 9

Growth Habit

Perennial tree with a pyramidal to upright-oval crown. Can reach 60-80 feet in height with a spread of 40-50 feet. Medium to fast growth rate.

Bloom Season

Spring (April-May). Small, inconspicuous purple-green flowers appear before the leaves. It is dioecious (separate male and female trees).

Toxicity

Not generally considered toxic to humans, dogs, or cats. However, like many trees, the seeds or bark may cause mild digestive upset if ingested in large quantities by pets.

Propagation

Primarily by seed (requires cold stratification) or by grafting. Cuttings are generally difficult to root.

Common Pests & Issues

Emerald Ash Borer (EAB) is a devastating pest. Also susceptible to ash yellows, anthracnose, and various leaf spots.

Similar Species

Green Ash (Fraxinus pennsylvanica) is very similar; Green Ash usually has leaflets that are more serrated and lack the whitish undersides of White Ash. Box Elder (Acer negundo) has similar compound leaves but opposite branching and 'helicopter' seeds (samaras) in pairs.

Interesting Facts

White ash wood is the standard material used for professional wooden baseball bats because it is strong, straight-grained, and has high shock resistance.
