Plant Family: Olaceae
Plant Description: A recent introduction, this medium-sized deciduous tree is a cross between the Manchurian ash and the black ash. It's compound leaves are attractive with slightly rounder edges than the green ash. This tree is most striking in the fall when the cooler temperatures cause the leaves to achieve a golden hue. It grows well in alkaline soils, but needs moderate water to thrive.

Maintenance:

Maintenance Type: Tree - Deciduous
Plant Care: Tree - Deciduous (single-stemmed woody plants that lose their leaves every winter): Prune regularly to promote health, provide air circulation, maintain a desirable shape, and to remove dead or damaged branches. Pruning is best done in late winter to early spring for most trees. With spring blooming trees, prune after the blooms are spent. Choose species that are resistant to pest damage. Monitor the tree for pests, diseases or other ailments on a regular basis. Protect the trunk especially where maintenance activities, such as mowing, may cause damage. Newly planted trees in areas with high exposure should have the trunk protected during the winter.
