Native to Wisconsin’s woodlands and forests, Pagoda Dogwood is an incredibly useful small tree or large shrub that provides year-round interest in the landscape. 2-inch clusters of slightly fragrant flowers in spring give way to blue-black berries on red peduncles (flower stalks) in summer, a favorite of native wildlife. Maroon fall color and an attractive, horizontal-tiered branching structure with deep purple twigs round out the year to provide interest throughout the seasons.

Use Pagoda Dogwood as a small specimen tree in landscape beds, especially near entries or patios, or as part of a large shrub border. As a native understory plant, this tree is especially appropriate in shady naturalized areas or woodland gardens underneath shade tree canopies.
As a bonus, Pagoda Dogwood is also deer-resistant and can tolerate planting near Black Walnut trees.
Pagoda Dogwood is utilized by many birds, insects, and mammals as both a food source and for cover. Birds, including game birds such as grouse, pheasants, and turkeys, and small mammals enjoy the summer berries. Many pollinators and butterflies will visit the spring flowers, and this tree is a larval (caterpillar) host for the Spring Azure.
Deer tend to avoid this plant, so it’s a good choice where deer damage is a concern.
Site Pagoda Dogwood in a protected landscape bed with plenty of organic material and organic mulch, such as shredded bark or leaves. This plant is most happy in part-shade conditions where the soil stays cool and moist, but it can tolerate full sun if moisture and mulch are maintained for cooling of the roots. Planting directly in the lawn or in a site where the tree is subject to strong winds is not recommended.
Since Cornus alternifolia has a distinctive shape, prune selectively to emphasize the look while the tree is dormant during winter or very early spring. It can also be pruned of lower branches to create a single-stem specimen.
This plant may self-seed, but any seedlings are easily pulled as they emerge.
Pagoda Dogwood is prone to a small number of issues, primarily fungal diseases such as powdery mildew and leaf spot during wet years. These are usually cosmetic issues and don’t require treatment. Removing damaged or diseased leaves from your property in fall will help avoid recurrence the following year.
Cankers and stem die-back can also be a concern. Prune affected stems at ground level, or several inches below the canker. Keeping Pagoda Dogwood well-watered with plenty of air circulation will help the plant stay healthy and reduce susceptibility to disease
Pagoda Dogwood gets its common name due to the fact that the horizontal tiers of branches resemble the multiple stories of a pagoda, the tower-like structure commonly found in East and South Asia. Unlike most Dogwoods, the leaves of Pagoda Dogwood are arranged alternately rather than oppositely on the stem, hence its botanical name Cornus alternifolia (i.e. alternate foliage).
Pair Pagoda Dogwood with shade-tolerant ground covers, such as Canada Wild Ginger, Pennsylvania Sedge, Sweet Woodruff, or perennial geranium. Native perennials such as Canadian Columbine and spring ephemerals like Triliums also combine beautifully with Cornus alternifolia in a naturalized area. For use in large shrub borders, try mixing this plant with other natives like Gray Dogwood, Common Witchhazel, and Common Ninebark.
