Status:

Common Greenbrier is the most common species of greenbrier in Maryland. It grows "[i]n almost any habitat, rocky, dry or wet, and open sun to moderate shade in thickets" (Brown and Brown, 1972). It is a pioneer species that grows well in disturbed areas, forming tangled patches when support is lacking. It is able to resprout from its slender rootstock in response to fire, and has been known to come in aggressively after controlled burns.

Description:

Common Greenbrier is dioecious, with male and female flowers on separate vines. It is very thorny and climbs by tendrils, forming thickets that provide cover for birds and small mammals.

Where to find:

Throughout Maryland.

Relationships:

Host plant for various moth species including Spotted Phosphila Moth, Curve-lined Owlet Moth, Proleucoptera smilaciella, and Marmara smilacisella.

There is an undescribed species of gall-making midge in the genus Meunieriella that forms galls on Common Greenbrier.

There are 708 records in the project database.
