A medium to large deciduous tree native to eastern North America, prized for its fast growth and tolerance of wet or dry soils. Its feathery compound leaves turn yellow to burgundy in fall.

Why grow it

Green ash establishes quickly and handles both waterlogged and drought conditions better than many native hardwoods, making it useful for sites where soil moisture is unpredictable. It produces relatively fine-textured shade and modest wildlife value through its seeds and foliage. Compared to other eastern ash species, green ash tolerates alkaline soils and urban stress, though it lacks the superior form of white ash or the disease resistance of some alternatives.

Watch out for

Green ash branches are somewhat brittle and prone to storm damage, requiring pruning to develop a strong structure when young. The tree's shallow root system may compete aggressively with nearby plantings and can damage nearby hardscape in confined spaces.
