Hedera - Ivy - is an evergreen climbing or ground-creeping woody plant. When creeping, it rarely exceed 20 cm height, but when climbing on suitable surfaces,using specialised hairs that enable it to cling, it can climb to at least 30m above the ground. The leaves of ivy are shiny, dark green (pale green when young) with 3 - 5 lobes.Mature plants produce yellow-green flower-clusters, followed by black berries. All parts of the plant are toxic, and contact with the sap may irritate skin, or cause an allergic reaction.There are many cultivars. 'Royal Hustler' has a medium growth rate, and dark green slightly indented leaves.
