Plant of the Week: Kousa Dogwood
Kousa Dogwood (Japanese Dogwood)
The kousa dogwood (japanese dogwood) can be expected to grow in Hardiness Zones 5–8.
This tree is considered both a flowering tree and an ornamental tree. It is typically planted for both its visual interest and profusion of spring flowers.
The kousa dogwood grows to a height of 15-25' and a spread of around 25' at maturity.
This tree grows at a slow to medium rate, with height increases of anywhere from less than 12" to 24" per year.
Full sun and partial shade are best for this tree, meaning it prefers a minimum of 4 hours of direct, unfiltered sunlight each day.
The kousa dogwood grows in acidic, loamy, moist, sandy, well-drained and clay soils. It prefers average moisture but is somewhat drought-resistant.
Blooms May–June, with distinctive white bracts surrounding small, greeinish-yellow flowers.
Is a good choice for planting near utility lines, buildings or walls.
Features dark green leaves that are 2–4" long and elliptic-ovate in shape.
Has a beautiful form with horizontal branching.
Grows in a rounded shape.
Requires mulch around the trunk to protect it from lawnmower or weed cutter damage that could cause poor health.
Produces pinkish-red to red fruit that attracts songbirds.
Provides great fall color, with leaves turning purple and scarlet.
Is tougher than the native flowering dogwood when it comes to disease and pests.
Develops a camouflage pattern of tan and brown on the trunk due to exfoliation.
Kousa dogwood seeds are eaten by squirrels and birds.
