May 2020: Cornus florida, common name flowering dogwood

- Best grown in the part shade of an understory
- Deep shade or full sun is not recommended:
- Will grow in dense shade, although flowering will be minimal to none.
- Will grow in full sun, however, it becomes susceptible to scalding issues and other stresses.
- Dry to moderate soil moisture is best.
- Neither extreme drought nor wet sights are acceptable.
- Anthracnose and powdery mildew can be problematic. However, anecdotal evidence by McCoy Horticultural has found that foliar applications of good biologically active compost tea may provide suppression of foliar diseases.
- Deer resistance is low.
Ecological values:
- Attracts native bees
- Hosts Spring Azure (Celastrina ladon) caterpillar
- Attracts predatory or parasitoid insects that prey upon pest insects
- Improves soil (Its leaf litter decomposes more rapidly than most other species.)
- Seeds (high calcium and fat content) are consumed by many bird types including songbirds, forest edge species, and wild turkey, and small mammals such as the eastern chipmunk, white-footed mouse, gray fox, gray squirrel, black bear, beaver, white-tailed deer, and skunk.
- Beaver, rabbits, and deer browse the leaves and sprouts of the plant.
- Provides shelter and habitat for many wildlife species
Legal Status:
- Endangered in Maine, exploitably vulnerable in New York, and threatened in Vermont
