One of the most common invasives in Victoria is English Ivy (Hedera helix), a pervasive and fast-growing vine that sprawls across landscapes and climbs structures like trees and buildings. English ivy has a rapid growth rate and even grows in the winter because of its need for little light or water, making it a very successful invasive species. This ivy has two growth phases: the juvenile phase and the adult phase. The juvenile phase occurs when the plant grows along the ground and the leaves have five tips (photo 3). As the plant grows upwards it transitions into the adult phase, where the leaves change and become more egg-shaped, with roughly three tips. These photos were taken on the campus of the University of Victoria where the ivy has covered the forest floor and surrounding trees. For more information on English ivy, please visit the Invasives Species Council of BC’s website at https://bcinvasives.ca/invasives/english-ivy/.
