About English Ivy: An Invasive Plant in Maryland

Life cycle/information:
English ivy is an evergreen, perennial vine.

Growth habit: Fast growing and invasive. Leaves are dark green, waxy, and alternate along the stem. Leaf form is variable; usually three-lobed with a heart-shaped base. Mature leaves can be un-lobed and spade-shaped. Grows as a dense groundcover (juvenile stage) and a climbing vine (adult stage). Dense foliage blocks sunlight and restricts growth of other plants. Heavy vines cause damage and death to mature trees by loosening the bark and holding moisture against the trunk, making a good environment for fungal disease and decay. Heavy vines can take trees down in wind, snow, and icy conditions. English ivy also serves as reservoir for bacterial leaf scorch, a disease in maples, oaks, and elms.

Reproduction: Spreads by seeds and vegetative runners. Mature vines produce flowers and seeds, which are dispersed by birds.

Conditions that favor growth: Prefers semi-shady, moist soil but grows in many environments – woodlands, fields, forest edges, roadsides, and coastal areas. It also grows on and damages building façades.

What to plant instead: Groundcovers: Foam flower (Tiarella cordifolia), lady fern (Athyrium filix-femina), wild ginger (Asarum canadense) Vine: Virginia creeper (Parthenocissus quinquefolia)
