Now is the time of year when we start to notice vines climbing trees, crops, and even structures. While Wisconsin has over 50 plants categorizes as vines, bur (Sicyos angulatus L.) and wild (Echinocystis lobata (Michx.) Torr. & A.Gray) cucumber are two of the most common found in Wisconsin. If you see a vine that has small white flowers in August, chances are that it is one of these two species. While many characteristics are present to differentiate between the two, the easiest is to look at the leaves, as they are quite distinct.
