Growing Information
Origin Region
Native to most of Europe and southwestern Asia, extending from Spain to Russia and down to northern Iran.
Growing Season
Spring leafing, inconspicuous flowers in spring before leaves, winged seeds (samaras) maturing in late summer, dropping leaves in autumn to enter winter dormancy.
Sunlight & Water Needs
Prefers full sun to partial shade, requires moderate soil moisture, and does best in deep, fertile, well-drained soils while showing moderate tolerance to varying moisture levels once established.
Mature Size
Can reach a mature height of 80 to 120 feet with a spread of 50 to 80 feet; fast to moderate growth rate with a lifespan often exceeding 200 years under favorable conditions.
Special Characteristics
Valued for its tough, elastic hardwood timber historically used for tool handles and furniture. Exhibits good resilience in various urban and rural soils, though susceptible to modern forestry pests like ash dieback.
Wildlife & Ecology
Supports a wide variety of native insects, caterpillars, and moth species. Provides nesting habitat and cover for woodland birds, and the seeds are consumed by small mammals and birds.
