About Winter Creeper Euonymus: An Invasive Plant in Maryland

Life cycle/information: Winter creeper euonymus (Euonymus fortunei), also called creeping euonymus, is a perennial plant that grows as a groundcover, climbing vine, or sprawling shrub. It was introduced from China in 1907 for use as an ornamental evergreen groundcover. In 1994, the Maryland Department of Natural Resources reported it as being invasive in natural areas of Maryland. The Maryland Department of Agriculture (MDA) named winter creeper a Tier 1 invasive plant, as of February 2018. This classification means that a person may not propagate, import, transfer, sell, purchase, transport, or introduce any living part of a Tier 1 invasive plant in the state of Maryland. See the MDA website for additional details.

Growth habit: Winter creeper euonymus is highly variable in its growth habit and appearance. Leaves are evergreen, about 1 inch or less in length, crenate-serrate along the margin, and arranged oppositely along the stem. Leaf color is variable, usually dark green with silver-toned veins. Climbing stems form aerial roots, similar to English ivy.

Winter creeper can be 4-12 inches tall as a groundcover or as high as 70’ as a climbing vine. These plants can also grow in the form of mounding, woody shrubs. The groundcover form restricts growth of native terrestrial plants and the vining form can climb and kill small trees.

Reproduction: Adult plants produce a ⅓” diameter pinkish capsules that open to expose orange seeds in October-November. Birds and other animals aid in seed dispersal. Winter creeper also spreads vegetatively from the roots.
