Imperial Honeylocust

Gleditsia triacanthos 'Impcole' IMPERIAL

Plant Details:

Plant Type: Deciduous Tree
Plant Family: Fabaceae
Plant Description: Medium sized rounded deciduous tree. Although the species has thorns and large pods, this variety has no thorns and does not usually produce pods. The leaves are fernlike and composed of numerous leaflets making fall clean-up easy. The green rounded leaflets have serrated edges and will turn yellow in autumn. Flowers are yellow and insignificant. Very tolerant of dry and compacted soils as well as periods of drought and excess moisture. Provides light shade.
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.
