Alternate leaf dogwood

It is rare in the southern United States. It is commonly known as green osier, alternate-leaved dogwood , and pagoda dogwood. It is a shrub or small tree rarely exceeding feet in height with a diameter of inches.


Alternate-leaved Dogwood is found scattered throughout the province. It has a low spreading crown made up of nearly horizontal branches and numerous short smooth upright twigs and branch-lets. Description: Alternate leaf dogwood is also known as pagoda dogwood for its tiered horizontal branching.

It is used as an ornamental shrub or small tree. Elliptic-ovate, medium green leaves (to 3-5” long) turn reddish-purple often tinted yellow or green in fall. Although the leaves of most species of dogwood are opposite, those of pagoda dogwood are alternate , hence the specific epithet and often used common name of alternate-leaf dogwood.


In the fall, dogwood leaves add to the charm of the tree by changing to bright colors. Flowering dogwoods , Pacific dogwoods , red-osier dogwoods and rough-leaf dogwoods turn red. The alternate-leaf dogwood leaves change to reds and yellows. Bark and twigs are green to reddish-purple.


Wide, flat-topped clusters of fragrant, white-cream flowers become clusters of reddish-purple berries. Fall foliage is a dull maroon.
