Carolina Snailseed: A Native Vine with Unique Seeds

Carolina snailseed (Cocculus carolinus) is a native vine often noticed in fall for its clusters of bright red berries. The leaves resemble smilax or large-leaf vinca, but the plant’s namesake feature is hidden inside the fruit.

Identification

Clean the pulp from the red berries to reveal a single seed that looks remarkably like a tiny snail shell—hence the common name.

Ecology and Landscape Potential

Dr. Michael Dirr notes that Carolina snailseed was unknown to him until he came to Georgia. While it’s a native species with ornamental appeal, it reproduces aggressively, which limits its cultivated use unless a less prolific form is bred.
