Euphorbia sieboldiana ‘Erytrea Variegata’ is a rare and eye-catching variegated form of Euphorbia sieboldiana, a compact, herbaceous species native to East Asia. Known for its creamy variegation and elegant form, this variety combines the sculptural charm of Euphorbias with a softer, more decorative touch, making it an excellent collector’s plant for both indoor and outdoor settings.

This cultivar produces slender, upright stems topped with oblong to lance-shaped leaves that are beautifully variegated in shades of green, cream, and sometimes soft yellow or pale pink. The delicate colour pattern gives each plant a unique marbled or striped appearance. In late spring to early summer, it may also produce clusters of small greenish-yellow cyathia (Euphorbia flowers), adding extra seasonal interest.

Compact, resilient, and architectural, Euphorbia sieboldiana ‘Erytrea Variegata’ is perfect for bright windowsills, container displays, or sheltered gardens, where it provides subtle colour and structure year-round.

Euphorbia sieboldiana ‘Erytrea Variegata’ – Care Guide

Light

Prefers bright, indirect light to full sun. Indoors, place in a bright spot such as an east- or south-facing window. Outdoors, it thrives in full sun to partial shade. Strong light enhances the creamy variegation.

Watering

Water moderately during the growing season (spring and summer), allowing the top 2–3 cm of soil to dry out between waterings. Reduce watering in winter when the plant is dormant. Avoid overwatering — like all Euphorbias, it prefers slightly dry conditions.

Temperature and Humidity

• Temperature: Prefers 18–28°C. Protect from frost; minimum temperature 10°C.

• Humidity: Adapts well to normal indoor humidity; no misting required.

Soil and Potting

Use a gritty, well-draining cactus or succulent mix. Ensure the pot has drainage holes to prevent waterlogging. Repot every 2–3 years in spring, using a slightly larger pot if the roots have filled the existing one.

Feeding

Feed monthly during spring and summer with a diluted cactus fertiliser to encourage healthy growth. Stop feeding in winter.

Pruning and Maintenance

Remove any dead or damaged leaves or stems to keep the plant tidy. Handle with care and gloves, as Euphorbias exude a milky sap that can irritate skin.

Growth and Maturity

A slow-growing species that typically reaches 20–40 cm in height. Over time, it forms neat, upright clusters.

Common Issues

• Soft or rotting stems: Overwatering or poorly draining soil.

• Faded variegation: Insufficient light.

• Scorched leaves: Excessive, harsh sunlight.

• Pests: Occasionally mealybugs or aphids.

Background and Benefits

The variegated form, ‘Erytrea Variegata’, offers a refined twist on the species, combining Euphorbia’s signature resilience with elegant, creamy foliage.
