About This Species

Zone 6a BC Native

Grow me instead of Tree of heaven

This native tree can grow to 18 – 24 m tall and 15 m wide, making it a lovely specimen tree for large yards and open spaces. Tolerant of moist and wet soils, Oregon ash has leaves with many small leaflets and green flowers with bunches of hanging ‘helicopter’ seeds. Oregon ash is a deciduous tree- its leaves turn yellow and drop in the fall. It prefers sun or part shade. An interesting fact about this tree – it is very popular as a horticultural species in Europe!

When selecting non-invasive plants for your garden, be sure to look for those that are suitable for your location, including moisture requirements, hardiness zone, and avoidance of known bear attractants among other factors.
