Similar Species Guide

Mile-a-minute vines are easily distinguished from other vining plants by their triangular leaves, distinctive prickles or barbs, and large, obvious ocrea (see species identification page for photos of these traits).

Other plants, particularly other vines, may be confused with mile-a-minute. Please use the guide below to help identify other vines which are generally native, non-invasive species. For advice and information on how to manage these plants in your garden or yard, contact UConn’s Home and Garden Center or your local County Master Gardener’s Program.
