'Emerald Gaiety' is a named cultivar of the Euonymus fortunei plant, a broadleaf evergreen shrub commonly called wintercreeper euonymous. It belongs to the staff-tree family, making it a relative of bittersweet vines, and like bittersweet, it can be invasive in some regions. 'Emerald Gaiety' is a tough plant that tolerates drought conditions and the pollution of urban settings. The shrub forms a mounding shape, with branches that sprawl. It can be grown as a shrub, a spreading ground cover, or as a climbing vine.
Like many varieties of E. fortunei, 'Emerald Gaiety' has variegated foliage, but unlike the green and yellow/gold of other cultivars, this one blends green with white margins on its leaves. The creamy white margins take on a pinkish tone in fall as cold weather approaches.
Classified as a shrub/ bush with upright-growing branches, 'Emerald Gaiety' can be planted as a screen or informal hedge if kept trimmed. But it can also be grown as a vine or ground cover if you allow it to grow unchecked. As a ground cover, it is planted in mass and allowed to gradually take over a space through drooping branches that take root where they touch the ground. To grow it as a vine, you will need to provide support and be prepared to train the branches and tie them up with twine or tape.
As an evergreen, this shrub holds some potential for visual interest in winter. But if you live in a region that can receive heavy snowfalls, you will want to train it to grow up a support, thus raising it above snow level.

How to Grow 'Emerald Gaiety' Euonymus
Grow this shrub in full sun to partial shade. The other members of this species that display green and gold or yellow variegated leaves tend to have their best color when grown in full sun, but the color variegation is better on 'Emerald Gaiety' when it receives a bit of shade.
As with any variegated shrub, you will need to be on alert for reversion— branch new branches with solid green leaves with no sign of variegation. These shoots should be pruned off as soon they appear otherwise, the entire plant can revert to all-green foliage and lose its distinctive creamy white variegation.
Where long stems touch the ground, they easily root themselves, so you need to be on alert to remove these if you don't want the shrub to spread.
Variegated forms of euonymus such as 'Emerald Gaiety' prefer part sun and part shade conditions.
This plant prefers average, well-drained soil that is somewhat on the alkaline side. It does not do well in wet soil.
Euonymus plants need plenty of water as they are establishing, but once mature they have a good tolerance for drought conditions. A brief rainfall or watering every few weeks is all that's required for mature plants.
Temperature and Humidity
All forms of Euonymus fortunei have a good tolerance for all temperature and humidity variations found throughout their hardiness range. Ice can sometimes cause damage in winter, but the plants easily recover.
'Emerald Gaiety' generally thrives without any feeding at all. In poor soils, a fall application of fertilizer over the root zone might help the plant's vigor.
Propagating 'Emerald Gaiety' Euonymous
'Emerald Gaiety' is easily propagated with semi-hardwood cuttings:
- In late summer or early fall, take an 8- to 12-long cutting that contains both leaves and a portion of hardwood stem. Cut just below a growth node.
- Cut the stem into 3- to 4-inch lengths and pull the leaves off the lower half of each segment.
- Embed the end of each cutting into a seedling container containing a moistened mixture of peat moss and coarse sand or perlite.
- Cover the pot with a plastic bag to create a mini-greenhouse, and place it in a spot with bright, indirect light. Periodically remove the pot and check for root growth by probing the soil with a knife.
- When the roots are about 1 inch long (this generally takes about six to eight weeks) remove the pot from the plastic bag and continue growing in bright direct light.
- Keep the soil lightly moistened through the winter.
- Plant the specimen in the garden the next spring when the danger of frost has passed.
Consider these cultivars of Euonymus fortunei which have many of the same virtues as 'Emerald Gaiety':
- E. fortunei 'Emerald 'n' Gold' grows 1 to 2 feet tall with 2 to 4 foot spread; it has green leaves edged in yellow.
- Euonymus fortunei 'Colorado' is a pure groundcover, growing to only 9 inches tall with a spread of 1 to 2 feet. The solid green leaves turn purple in fall.
Remove stems that revert to all-green leaves. To shape this plant, do so immediately after the plant blooms in late spring.
Common Pests/ Diseases
'Emerald Gaiety' euonymus is a tough plant, and the main challenge is to control its spread. For example, the Missouri Botanical Garden recommends against using this plant in landscaping due to its invasive behavior in that region. To control the plant, remove offshoots that root themselves from branches that touch the ground, as well as shoots spreading out from the root ball.
Euonymus plants are quite susceptible to scale insects. Treatment takes place only when the scale insect eggs hatch in April and May into first instar nymphs called crawlers. A second generation of crawlers is produced during late July through August. Spraying crawlers with Neem oil (it is organic) can be effective in controlling scale insect infestations.
