Winter daphne (Daphne odora 'Aureomarginata')
Daphne odora 'Aureomarginata', the Winter daphne, is a highly fragrant, variegated broadleaf evergreen prized for late winter color and scent.
Complete Plant Information
Overview
Daphne odora ‘Aureomarginata’, commonly known as Winter daphne, is a highly valued broadleaf evergreen recognized primarily for its intensely fragrant blooms appearing when most gardens are dormant. This cultivar features glossy, dark green leaves edged prominently in gold, adding year-round variegated interest to the landscape. It’s a relatively compact shrub, typically reaching 3 to 4 feet tall.
The chief appeal of this Daphne lies in its late winter floral display—showy, reddish-purple flowers that perfume the cool air. While highly ornamental, successfully growing Daphne odora ‘Aureomarginata’ requires careful attention to its specific cultural needs, particularly concerning drainage and winter protection, making it a high-maintenance addition.
Growing Winter daphne successfully means mimicking its native habitat of China and Japan by ensuring sharp soil drainage and providing shelter from harsh conditions. Where hardy (Zones 7-9), this plant offers unmatched seasonal beauty, serving as an excellent foundation planting or accent specimen near walkways where its fragrance can be fully appreciated.

How to Grow
Planting Daphne odora ‘Aureomarginata’ should occur during cooler times of the year, allowing roots time to establish before the stress of summer heat. Site this shrub where it receives part shade, avoiding direct, hot afternoon sun which can scorch the variegated foliage. Sharp soil drainage is not optional; this plant demands rich, well-drained, sandy-humusy soil with a neutral pH. Gardeners in areas where winter is a threat should seriously consider raised beds if heavy clay soils are present, ensuring water never pools around the root zone.
Watering for Winter daphne must be consistent, aiming for medium moisture levels; do not allow the soil to dry out completely, especially during establishment and the summer months, as dry soil reduces subsequent bloom potential. While established plants show minor drought tolerance, consistent moisture is key. Daphnes resent disturbance, so select the final planting location with care, as they are often slow to establish and prefer to be left undisturbed once sited.
Winter protection is crucial, particularly near the hardiness limit of Zone 7. In colder margins or midwestern climates struggling with cold winters, locate Daphne odora ‘Aureomarginata’ on the south side of a structure, sheltered from abrasive winter winds. Container culture is an excellent alternative, allowing the gardener to move the plant into a greenhouse or sunporch to fully protect it from temperatures dipping below 10°F. Applying a winter root mulch can also help buffer changing soil temperatures.
Landscape Uses
The evergreen structure and variegated leaf margins of Daphne odora ‘Aureomarginata’ make it a superb choice for year-round visual appeal, whether utilized as a low, rounded hedge or a specimen against a contrasting wall. Plant this highly fragrant shrub near entryways, patios, or outdoor seating areas to maximize enjoyment of its late winter fragrance when few other plants are active. It serves perfectly as an accent in foundation plantings, softening hard architectural lines while providing texture.
When designing with this temperamental beauty, group it with plants that share similar needs for sharp drainage and part shade, such as various ferns or hellebores. While excellent near structures for winter protection, avoid placing it where it might receive reflected heat or harsh winter winds. Mass plantings of several Winter daphne specimens create a stunning, fragrant display throughout the late winter and early spring season.

Noteworthy Characteristics
Daphne odora, commonly called winter daphne because of its late winter flowers, is a broadleaf evergreen shrub that is native to China and Japan. It typically grows to 3-4’ tall and to 2-4’ wide. It features intensely fragrant reddish-purple flowers with pale pink to white insides in terminal inflorescences. ‘Aureomarginata’ is a variegated form featuring, as the cultivar name suggests, green leaves with yellow leaf margins, offering enhanced hardiness over the standard species.
Tolerances
- Soil Drainage: Requires sharp drainage
Potential Problems
Daphnes in less-than-ideal zones, like St. Louis (Zone 6a), often experience significant winter injury when exposed to severe cold or wind, which subsequently weakens the plants and makes them more susceptible to various ailments. Potential diseases include crown rot, root rot, botrytis, canker, and leaf spots, especially in poorly drained soil. Common insect pests to watch for include scale, mealybugs, and aphids. Because plants can be unpredictable—sometimes dying quickly without clear cause—prevention through perfect cultural placement is the best defense against most problems in growing Daphne odora ‘Aureomarginata’.
Frequently Asked Questions
What hardiness zones is Winter daphne suitable for?
Daphne odora ‘Aureomarginata’ is reliably hardy in USDA Zones 7 through 9, though special winter protection may be needed near the Zone 7 boundary.
How large does Winter daphne grow?
This broadleaf evergreen typically matures to a height between 3 and 4 feet, with a spread ranging from 2 to 4 feet wide.
What sun exposure does Winter daphne need?
This shrub performs best when situated in part shade; full, direct sun, especially during hot summers, can cause the foliage to scorch.
When does Winter daphne bloom?
The intensely fragrant, showy flowers of Winter daphne generally appear from March into April, depending on the specific locale within its hardiness range.
Conclusion
The Daphne odora ‘Aureomarginata’ offers gardeners an unmatched combination of glossy, variegated foliage and intoxicatingly fragrant flowers during the late winter months. While its high maintenance level and rigid soil requirements demand specific cultural conditions, the reward is a stunning evergreen accent. Before planting, verify your USDA zone and ensure you can provide impeccable drainage to give your Winter daphne the best chance for success.
Companion Planting
When selecting companions for Daphne odora ‘Aureomarginata’, focus on plants that share a preference for part shade and, critically, that do not compete heavily for the same sharply drained soil profile. Shade-loving perennials like Helleborus (Lenten Rose) are excellent partners, blooming around the same time or slightly later, and thriving in similar dappled light conditions. Groundcovers that prefer good drainage, such as Pachysandra or Vinca minor, can help maintain consistent soil moisture around the daphne’s roots without causing saturation.
Consider the texture contrast provided by ferns, especially Japanese Painted Ferns, whose delicate, silvery fronds offer a beautiful textural juxtaposition to the leathery, broad leaves of the Winter daphne. These companions should also be situated where they do not create dense competition immediately around the daphne crown, which requires good air circulation to mitigate fungal issues common to this genus.
Design Ideas with Variegated Shrubs
The yellow margin on the leaves of this specific cultivar provides bright contrast, making it a superb structural element in shade gardens where light is limited. Use Daphne odora ‘Aureomarginata’ near stone pathways or retaining walls where the varied light patterns throughout the day will highlight its variegation. Planting multiples in a staggered grouping—rather than a rigid line—creates a naturalized, soft border.
For containers, employ a “thriller, filler, spiller” method centered around the daphne as the structural thriller. Pair it with shade-tolerant annuals like deep purple Coleus or light-colored Impatiens as fillers, which will offer summer color while the daphne’s evergreen structure anchors the pot through the winter. Remember that container growing provides superior control over soil drainage, often making container culture the most reliable method for this plant outside ideal zones.
