Cotinus coggygria 'Royal Purple'

Plant Details:

Plant Type: Deciduous Tree
Plant Family: Anacardiaceae
Plant Description: Small tree or large shrub growing to 15' tall. Oval leaves are dark-red to purple throughout the summer turning scarlet red in autumn. Produces plume-like panicles of red to purple flowers that resemble clouds of smoke around the tree. May grow irregularly and grows best if planted in full sun. Tolerant of drought once established.

Maintenance:

Maintenance Type: Shrub - Renewal
Plant Care: Shrub - Renewal (woody multi-stemmed plants that lose their leaves every winter and look best on younger stems, which emerge from the base of the plant): 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 shrubs. With spring blooming shrubs, prune after the blooms are spent. When pruning, remove 1/3rd of the oldest branches by cutting at the base of the shrub. Monitor for pests, diseases or other ailments on a regular basis.
Special Considerations: This plant can be cut nearly to the ground every few years to encourage a fresh burst of foliage.
