Aralia (Eleutherococcus sieboldianus 'Variegatus')
Eleutherococcus sieboldianus 'Variegatus', commonly called Aralia, is a versatile, suckering shrub perfect for low-maintenance, shaded landscapes.
Complete Plant Information
Overview
Eleutherococcus sieboldianus ‘Variegatus’, often referred to simply as Aralia, is highly valued by gardeners for its resilience and striking foliage, particularly in challenging shade situations. This adaptable deciduous shrub puts on a reliable display with palmate leaves edged in brilliant white variegation, making it a standout even when out of bloom. It is renowned for thriving where other plants struggle, tolerating a wide spectrum of soils and urban conditions.
This specific cultivar is generally more compact than the standard species, reaching heights between 6 to 8 feet, and features arching stems that contribute to an attractive, informal shape. While it produces small, inconspicuous greenish-white flowers in late spring, the primary garden interest of Eleutherococcus sieboldianus ‘Variegatus’ lies in its year-round texture and color contrast, complemented by its very low maintenance requirements.
Its adaptability makes this Aralia an excellent choice for mass plantings, developing into dense screens or naturalized areas within woodland settings. Gardeners appreciate the Eleutherococcus sieboldianus ‘Variegatus’ for its ability to provide structure and light contrast in deep shade gardens with minimal long-term input.

How to Grow
Planting Eleutherococcus sieboldianus ‘Variegatus’ is flexible; it readily establishes in spring or fall. This incredibly adaptable shrub readily handles a wide range of soils, preferring locations that offer part shade to full shade, although it tolerates more sun if adequately watered. Ensure the planting site is adequately prepared, keeping in mind that this five-fingered Aralia benefits from routine removal of root suckers if a contained shape, rather than a naturalized thicket, is desired.
Once established, the water requirements for this species are low, handling drought conditions well thanks to its robust root system. Fertilization is rarely needed unless the soil quality is exceedingly poor; focused feeding distracts from its natural, tough constitution. Pruning is generally only required to control size or remove any reverting green stems that lack the signature variegation.
This shrub shows excellent tolerance to urban pollution and resists major pest or disease issues, contributing to its low-maintenance rating. In winter, deciduous shrubs like this Aralia require little specific preparation, though ensuring deep watering before the ground freezes solid can help prevent winter desiccation.
Landscape Uses
The architectural foliage and excellent shade tolerance make Eleutherococcus sieboldianus ‘Variegatus’ invaluable in foundation plantings and shrub borders, providing necessary structure where few other shrubs perform well. Its eventual height and spread of up to 8 feet make it an effective, albeit softly textured, natural screen or hedge. The sharp thorns along the nodes, which give it a “hedge-row like quality,” enhance its utility when used as a protective barrier.
For design purposes, the bright, variegated leaves of the Aralia pop against darker green evergreens or deep purple foliage plants often used in shade gardens. They serve beautifully as informal backgrounds for collections of hostas, ferns, or woodland perennials that require protection from intense afternoon sun.
Consider naturalizing large groupings of Eleutherococcus sieboldianus ‘Variegatus’ under mature deciduous trees where leaf litter might suppress lawn growth. This allows the shrub to form its natural, suckering habitat while providing excellent ground coverage and seasonal structure, embracing its lesser maintenance needs.

Noteworthy Characteristics
Eleutherococcus sieboldianus commonly called five-fingered (or fiveleaf) aralia, is an upright, suckering, deciduous shrub growing 8-10’ tall with arching stems and buckeye-like, palmate foliage. Small greenish-white flowers appear in umbels in spring, but are inconspicuous. Flowers on female plants (species is dioecious) may give way to small black berries if properly pollinated, but most plants sold in cultivation are females so fruit is rarely seen. Sharp thorns appear at the stem nodes below each leaf. ‘Variegatus’ is more compact than the species, typically maturing to 6-8’ tall, and features striking variegated foliage in which the palmate leaves (leaflets to 2” long) are bright green edged with white, providing excellent contrast in shady areas.
Tolerances
- Drought
- Dry Soil
Potential Problems
This cultivar generally experiences no serious insect or disease problems, contributing significantly to its low-maintenance appeal across USDA Zones 4 through 9. Gardeners should remain vigilant, however, for any instances of reversion where the white edging disappears from the leaves; these solid green shoots can grow more vigorously and should be pruned out immediately to maintain the desired ‘Variegatus’ appearance.
Frequently Asked Questions

This deciduous shrub typically matures to a height and spread between 6 and 8 feet, though the species can be slightly taller.
What sun exposure does Aralia need?
This plant thrives best in part shade to full shade conditions, making it an ideal structural plant for darker corners of the landscape.
When does Eleutherococcus sieboldianus ‘Variegatus’ bloom?
The bloom time for this Aralia is generally from May to June, producing inconspicuous greenish white flowers.
Conclusion
The utility of Eleutherococcus sieboldianus ‘Variegatus’ lies in its unparalleled adaptability, offering bright, variegated foliage in low-light, low-care environments. This tough Aralia proves that shade gardening does not require constant fuss, handling drought and poor soils with ease. Before planting, confirm your location falls within USDA Zones 4-9 and prepare to enjoy years of vibrant texture from this robust shrub.
Companion Planting for Shade Gardens
Since Eleutherococcus sieboldianus ‘Variegatus’ prefers dry to medium moisture and part shade, select companions that share similar low-maintenance requirements. Hostas with dark blue or deep green foliage create a beautiful contrast against the white margins of the Aralia leaves. Lungworts (Pulmonaria), which tolerate dry shade once established, also pair well, offering early spring color near the base of the shrub.
Consider using groundcovers that spread slowly to define the edges of a grouping of Aralia without competing aggressively for nutrients in dry shade. Creeping Jenny (Lysimachia nummularia ‘Aurea’), while sometimes needing more moisture, can offer bright color beneath the shrub if kept consistently watered during establishment periods.
Design Ideas Using Variegation
The bright edge on the leaves of Eleutherococcus sieboldianus ‘Variegatus’ helps illuminate dark areas of the garden, acting as a natural reflector of available light. Use this quality strategically near pathways or patios where visual impact is desired, even after the bright flowers of spring have faded.
For formal uses, the inherent thorniness and adaptability to shearing make it a functional, if slightly wilder, alternative to traditional boxwood hedges in deep shade. For a more naturalistic woodland effect, allow the plant to sucker slightly, mingling it with native ferns and shade-loving astilbes to create textural drift patterns.
