CORNUS. Dogwood. Widespread in North America, Europe and Asia. This is a sizeable group of shrubs and trees, including some of our best-loved ornamentals. The shrubby sorts have generally long, wandlike stems, often making broad thickets. Some of the trees have their branches arranged in horizontal tiers, giving a distinctly oriental effect. In either case, they have large pointed-oval leaves, normally paired along the stems and conspicuously veined. The flowers are small, clustered in many species like those of the viburnums. The white to red, blue or black berries which follow also resemble those of the viburnums. Several species have the true flowers clustered more tightly into a central ball, surrounded by large, usually white or pinkish bracts, which most gardeners see as the flower. Many are deciduous and among the most colorful of all trees and shrubs in the fall. All have attractive winter silhouettes, and some, like C. sibirica, extend the show with brightly painted bark. Sun or light shade, well drained, non-alkaline soil and regular watering except as described below. Their hardiness varies as described.

capitata. Evergreen dogwood. A bushy small tree, nearly round to pyramidal in silhouette and up to 30’ (occasionally more) tall. It has evergreen greyish green leaves and produces clouds of blossoms, with cream-colored to pale yellow bracts up to 4" across, in late spring and early summer. Hardy to 15oF or less.

kousa. A bushy tree 20-30’ tall in age. It holds its branches nearly erect, though nearly hidden on younger plants by dark green 1½" leaves. White, four-bracted flower clusters, the bracts about 3" across, decorate the plant in summer and develop by fall into equally decorative, pendant clusters of bright red berries. Probably 0oF.

omeiense ‘Summer Passion’. I still have only sketchy information on this new dogwood from Piroche Nurseries in Canada. It is described as an evergreen species, up to 30’ tall. The main trunk is upright, the branches spreading to create a shapely head. The leaves are narrow-oval in outline and about 3" long on our plants. They are painted with orange and red in new growth, changing to dark green with a bronze overlay and glossy surface when mature. The small, clustered flowers are light yellow in color. I have not yet seen the berries. Probably 10-15oF.
