Plant Profile: Euonymus fortunei

Climbing Euonymus is a shrub that exhibits climbing characteristics similar to a vine. In its juvenile stage, it acts as a sprawling groundcover, while in its mature form, it develops into a shrub. This plant is commonly found in the woodlands and thickets of the low mountains in its native Japan. Various cultivars exist, some leaning more towards a vining habit and others resembling small shrubs; however, it is important to note that both the vining types and certain shrubs can be invasive. Climbing Euonymus often escapes cultivation and can easily overtake medium-sized trees. It is recognized as an invasive species in North Carolina and several other southeastern and northeastern states. When utilized as ground cover for its attractive foliage, it tends to climb if provided with support. As a woody vine, it can generate new rootlets when its branches touch moist soil, and it also produces aerial rootlets along its branches when climbing trees. This plant is frequently affected by deer and demonstrates a tolerance for salt.

While there are no documented cases of toxicity for this particular species of Euonymus, several plants within this genus are known to be poisonous, so caution is warranted. It is advisable to avoid consuming any part of this plant in large amounts, especially the berries, which should not be ingested by humans. However, these berries are consumed by certain birds, which aids in the plant's spread and contributes to its invasive nature.

Creeping Euonymus exhibits variable growth, reaching heights of up to 6 feet as a shrub or spreading to 20 feet as a branching woody vine when supported by structures like walls, trees, or trellises. As ground cover, it can be maintained at a few inches tall, pruned to a height of two to four feet as a small shrub, or allowed to grow around 15 feet as a standard vine on a trellis. If climbing a tree in search of sunlight, the vine can extend well beyond 15 feet. The subspecies E. fortunei radicans is particularly valuable, along with cultivars such as 'Emerald and Gold', 'Emerald Gaiety', 'Coloratus', and 'Kewensis'.

The leaves of Creeping Euonymus are semi-evergreen to evergreen and do not exhibit fall color changes. Variegated, colored, and green cultivars are available, although non-green varieties often revert to green. The plant produces long-lasting fall berries with orange arils (pulp), while adult plants bear small, inconspicuous flowers in the spring, typically greenish-white and measuring about a quarter inch.

Creeping Euonymus thrives in full sun to partial shade, preferring moist to dry-mesic conditions and soils that include loam, clay-loam, sand, and gravel. It can tolerate heavy shade, adapts to various pH levels, and is easily propagated from woody cuttings, thriving in a range of soil types except for overly wet conditions.
