Mountain dogwood is a California native shrub or tree found in the California Floristic Province, particularly less common in southern California, in forest habitats at elevations below 2,000 meters. Flowering from April to July, this plant produces showy white to greenish-white flowers with distinctive large bracts 4 to 6 centimeters wide that persist around the flower cluster. Growing up to 25 meters tall with green twigs and bark that turns dark red to nearly black with age, it develops an elegant, spreading form. Its leaves are narrow-elliptic to obovate, 6 to 12 centimeters long, with a lighter and hairier undersurface and a slightly puberulent upper surface. The fruit is an elliptic, generally angled red drupe 1 to 1.5 centimeters long with a smooth stone.
