Description Of all the different ash species in the ornamental trade, the cultivar 'Raywood' is known for its exceptionally striking wine red fall foliage. Often referred to as 'Claret Ash'.

  Morphology:
Raywood Ash grows 40’-50’ tall with a 25’ spread in a landscape, opening into a full, rounded canopy with age. On better sites this species can grow even taller and wider. The canopy is symmetrical with a smooth outline. The bold round-headed form is perfect to cast summer shade.

Leaves are arranged in a pinnately compound fashion. Leaves consist of 7-9 narrow leaflets, each of which are 1.5” to 2.5” long. Leaves are lanceolate in shape and have serrated edges.

During the summer foliage is dark green, but in the fall the notable purple foliage color begins

  Adaptation:
It should be grown in full sun and is moderately drought-tolerant once established. Although these trees can tolerate wet sites, they will perform much better in well-drained conditions. Surface rooting is reported to be a problem on wet sites.

  Pests:
None reported.
