Euonymus
fortunei
Euonymus or Wintercreeper Euonymus
(Celastraceae - Staff-Tree Family)
Form
- usually a small-sized, broadleaf evergreen, ornamental shrub, maturing at
2' to 4' tall by 2' to 5' wide (depending upon cultivar)
- the cultivar 'Colorata' is a broadleaf semi-evergreen woody groundcover,
to 1' tall when not near a supportive structure
- upright clump to spreading clump growth habit for shrub form cultivars,
and a procumbent mat growth habit for the groundcover 'Colorata'
- medium growth rate for both forms, slowing with maturity unless frequently
pruned
Culture
- full sun to partial shade (with the variegated forms performing best in
partial sun to partial shade)
- prefers moist, well-drained soils in partial sun, but tolerates poor
soils, various soil pHs, soil compaction, heat, drought, shearing, and
pollution, and is therefore urban tolerant
- propagated primarily by rooted stem cuttings
- Staff-Tree Family, with Crown Gall being the primary cosmetic disease
problem (rare occurrence, with age) and Euonymus Scale being the primary
cosmetic and life-threatening pest problem (common occurrence with age,
especially in mass plantings where it progressively spreads)
- shrub forms (primarily the variegated cultivars) are abundantly available
in containers, while the groundcover form is commonly available in flats
- rejuvenation shearing in early Spring for the variegated shrub forms will
keep their rapid growth in-bounds and result in more vibrant variegated
foliage
Foliage
- evergreen to semi-evergreen, medium to dark green leaves are moderately
shiny, with virtually no petiole
- opposite, elliptical, and finely serrated to crenate on the margins,
ranging from 1" to 3" long, depending upon cultivar
- most cultivars are foliage-color variants that have white, cream, gold, or
yellow variegation, usually at the leaf margin, but sometimes extending into
the leaf interior or down the midrib
- fall color is variable, becoming distinctly red-purple-bronzed for the
solid green-foliaged groundcover form 'Colorata', but having hues of dull
gray-green or pink in addition to the persistent but faded variegation for
the shrub forms, depending upon cultivar; leaves persist throughout Autumn
and some may slowly abscise during Winter, especially on the groundcover
form
Flowers
- cream-yellow or lime-colored flowers bloom in June or July, but are
usually not present or are ornamentally insignificant (except for some
unpruned green-foliaged shrub cultivars, which can have a subtle but nice
ornamental display)
Fruits
- dehiscent capsules that expose the small orange seeds in Autumn are often
ornamentally inconspicuous, if present at all
Twigs
- usually medium green with a hint of corkiness, changing to tan with age,
and either procumbent (for the groundcover form), or emerging from the
much-branched base as relatively unbranched and vertical (for the shrub
forms)
- stems, when placed next to a climbable structure (e.g. block or brick
foundation, chain-link fence, tall wooden timbers, etc.) will clasp to it
and take on a short clinging vine stature, irrespective of whether the plant
is a shrub form or groundcover form of the species
ID Summary
- opposite, elliptical, subtlety serrated broadleaf evergreen foliage is
often found in variegated form on the shrubs, or green but heavily bronzing
in Winter on the groundcover form
- foliage and stems form a dense canopy with maturity, but are eventually
subject to attack by scales, miniature white or gray ellipsoid structures
that have juice-sucking insects underneath an outer protective
"scale"
Function
- foundation, specimen, facer, low hedge, edging, or group or mass planting
shrub
- mass planting groundcover (if 'Colorata')
Texture
- medium texture in foliage
- thick density in foliage
Assets
- many variegated shrub forms, and one prominently-used groundcover form
- evergreen to semi-evergreen broadleaf character, often either variegated
(shrubs) or Winter-bronzing (groundcover)
- urban stress tolerant
Liabilities
- very prone to Euonymus Scale (often slowly lethal unless the insect
infestation is treated with pesticides and/or dormant oil, and always
unsightly as a white or gray "powder" on the stems and undersides
of the foliage), with a secondary infection of gray mildew occurring in
extreme cases
- both shrub and groundcover forms retain blown leaves due to the numerous
low, upright stems and retentive foliage
Habitat
- zones 5 to 9
- native to China
Variants
- an abundance of cultivars exist, selected for growth habit or variegation;
only the most common are noted below:
- Euonymus fortunei 'Colorata' - Purple Wintercreeper - probably the
most common broadleaf evergreen trailing groundcover after English Ivy (Hedera
helix), becoming intensely burgundy-purple in Winter (bronzing), often
found in raised planters, along sidewalks, or at foundations, where it may
also partially climb walls as a clinging vine for several feet in height;
otherwise growing to 1' high as a dense entangled groundcover mat; mulch
upon transplanting the plugs to achieve weed control and to prevent freeze
heaving of the shallowly rooted transplants during the ensuing Winter;
several selections of this form are being sold under the same cultivar name
in the nursery industry; also sometimes spelled 'Coloratus' or considered as
the variety colorata or coloratus
- Euonymus fortunei 'Emerald Gaiety' - a shrub that slowly matures at
4' tall by 6' wide if unpruned, but often frequently sheared back to contain
its vigorous vertical as well as spreading habit, with emerald leaves that
have a white to creamy margin, having a few prostrate branches from which
arise many vertical, unbranched stems; very popular
- Euonymus fortunei 'Emerald 'n Gold' - a shrub similar in all
respects to 'Emerald Gaiety' except that it has emerald leaves surrounded by
a striking gold to yellow leaf margin; also very popular
- Euonymus fortunei 'Green Lane' - a lustrous bright-green to dark-green
foliaged shrub form with slightly larger leaves, maturing at 4' tall by 6'
wide, with showy July flowers that give rise to light pink fruits, which
dehisce to expose interior orange seeds in Autumn; low availability
- Euonymus fortunei 'Sun Spot' - a shrub with a golden-yellow stripe
down the midrib of each dark-green leaf, with new stems also being yellow,
having a sprawling habit and slowly maturing to 3' tall by 6' wide
Purpose
- Euonymus is a popular small broadleaf evergreen shrub with many variegated
cultivars, or a bronzing semi-evergreen procumbent groundcover known as
Purple Wintercreeper.
Summary
- Euonymus fortunei is a variable growth habit species (small shrub
to groundcover form), usually found in variegated shrub form and utilized as
a broadleaf evergreen accent for foundations, edgings, or group plantings.
