Bushkiller vine, Cayratia japonica, has been found at 2 sites in Maryland, one in Anne Arundel Co. and the other in Baltimore (K. Kyde, MD DNR, 11/21/13). These are the northernmost known occurrences of this plant. This vine looks a lot like Virginia creeper, but the leaflets are not all attached to a central point. The lowermost leaflets occur in pairs. As it name implies, bushkiller vine can overtop shrubs blocking light to the shrub’s leaves. It climbs using tendrils.
