Description The green Ash cultivar ‘Summit’ is best known in the trade for its intense golden-yellow fall foliage. It is widely planted for it ability to form quick shade.

  Morphology:
This deciduous shade tree grows to 45’ in height and 25’ in width. It features a very uniform branching habit with a symmetrical oval canopy, all on a strong central leader. Leaves are pinnately compound, a foot long, and often have 7 leaflets. Each leaflet is 2”-4” in length and arranged in an opposite fashion. During the summer the foliage is medium green.

This cultivar is typically seedless, consisting predominantly of male clones.

  Adaptation:
As with other ash cultivars this variant does best in full sun to partial sun on moist well-drained soils. However it is very adaptable to poor sites and those that are drought prone.

  Pests:
Pest free on the West Coast.
