Starlight Dogwood

Starlight Dogwood (Cornus kousa x nuttallii 'Starlight')

Starlight Dogwood (Cornus kousa x nuttallii 'Starlight') is a vigorous, hybrid dogwood tree developed by the University of Washington for superior performance in landscapes. A cross between Cornus kousa and Cornus nuttallii, this tree combines the elegant form and disease resistance of Kousa Dogwood with the towering height and large floral display of Pacific Dogwood. The result is a majestic ornamental tree with exceptional presence and resilience.

Distinctive Features

'Starlight' is known for its large, overlapping white bracts that bloom in late spring, covering the tree in a dramatic floral show. Its dark green foliage remains attractive through summer and transforms into shades of red and purple in fall. The tree forms a symmetrical, upright-oval canopy and typically grows 25�30 feet tall and 15�20 feet wide. Unlike its Pacific Dogwood parent, 'Starlight' is highly resistant to anthracnose and performs reliably in urban and suburban settings.
