Hello from Long Island NY..looking for suggestion for ground cover that won't eat my plants. I would like somthing a bit tamer the vinca . The area is slightly damp..part sun/part shade. Any suggestions. See posted pics! Thanks!!The accompanying photos show a mix of young trees, shrubs, and perennials in a nice non-lawn streetside garden. The photos show a lot of sun, with some shade. The shade will increase over time as the trees and shrubs fill in.
Another commenter suggested Lamium and Galium, neither of which I would describe as "tame." Either can take over an area in the right conditions.
These are some of the Eastern North American species I've grown and can recommend as groundcover. Some of these prefer shade, some prefer sun. Most of these will spread by runners, stolons, and the like, as "true" groundcovers. Others are effective as groundcovers because of their habit and crown expansion over time.
