Additional information:
When they think of dogwood, most gardeners visualize the large bracts of the showy flowering dogwood (Cornus florida). Pagoda dogwood lacks the showy bracts, but the many white flowers hovering over the dark green leaves can still be very attractive. Unlike most members of the dogwood family that have opposite leaves, pagoda dogwood has an alternate leaf arrangement. The leaves of pagoda dogwood form an umbrella-like shade because they are clustered near the ends of twigs. Pagoda dogwood has greenish to reddish or purple to purple-brown stems. Older bark is gray and has slight ridges or furrows.
Culture: Pagoda dogwood prefers moist, acidic, well-drained soil. It appears to prefer partial shade but can grow well in full sun. It is important to keep the root zone cool and moist. Pagoda dogwood performs best in colder climates. It is hardy in Zones 3 to 7. It will tolerate only short periods of drought. Pagoda dogwood is susceptible to twig blight, leaf spot and canker.
