-
The Hybrid Flowering Dogwood is a cross between the Flowering Dogwood, Cornus Florida, and Kousa Dogwood, Cornus kousa, There are several cultivars available including 'Aurora,' 'Constellation,' 'Stellar Pink,' and 'Celestial.' These plants were developed by Elvin R. Orton, Jr of Rutgers University, and they are a part of the Stellar Series.
In the 1970s, our native Flowering Dogwood was severely impacted by anthracnose and was also susceptible to Dogwood borers. Dr. Orton crossed the two plants in hopes of developing a plant that would be resistant. In the 1990s, he introduced the Stellar Series. He also developed the fast-growing "Hyperion.' These plants are known to be resistant to borers and anthracnose. They are sometimes designated in commerce as Cornus x rutgersensis.
The genus name, Cornus, is Latin for the word, cornu, which means "horn." This references the hardness of the wood.
The Hybrid Flowering Dogwood is best grown in full sun to partial shade and in organically rich acidic soils. They prefer moist and well-drained soil. Mulching keeps the roots moist and cool during the hot summer.
Depending on the cultivar the height, width, habit, and flower color may differ. The cultivars are sterile.
Below are the descriptions of several of the popular cultivars.
- 'Aurora'--upright, showy creamy white overlapping flower bracts,
- 'Celestial'--dense, upright habit, up to 20 feet tall and wide, dark green leaves that turn purplish-red in the fall, blooms heavily, showy flowers emerge white tinged with green and mature to pink, small fruits are sterile
- 'Constellation'--low branching habit, up to 16-22 feet tall and 12-18 feet wide, oval dark green leaves that turn purplish-red in the fall, large showy white petal-like bracts, produces no fruit
- 'Stellar Pink'--dense, upright habit, up to 15-30 feet tall and wide, dark green leaves turn purplish-red in the fall, showy four-petaled pink flower, sterile and produces no fruit
The Flowering Hybrids are popular for home lawns and patios. They are attractive trees with showy flowers and would serve well as a specimen or in a small grouping.
Seasons of Interest: Foliage: Fall Bloom: Spring
Insects, Diseases, and Other Problems: Leaf miners and scale are less serious potential insect pests. These hybrids are resistant to anthracnose and Dogwood Borers.
