Hedera spp. (Hedera helix = English ivy, Hedera canariensis = Algerian ivy) are perennials (family Araliaceae) that grow as evergreen woody vines. Both plants are found throughout Calfiornia along the coast, as well as in Shasta and Butte Counties. Hedera spp. grows vigorously in forests where nothing else seems able to compete and inhibits regeneration of understory plants, including forest wildflowers and new trees and shrubs.

Cal-IPC Inventory rating: High
