Sansevieria cylindrica ‘Boncel Variegata’, also known as the Variegated Starfish Snake Plant, is a rare and highly decorative cultivar of the cylindrical snake plant family. Native to Angola, this succulent species has become a favourite among collectors for its compact, architectural rosette form and striking variegation.

The ‘Boncel’ variety produces thick, cylindrical leaves that fan out in a radial pattern resembling a starfish. The variegated form is even more spectacular, with irregular streaks, marbling, and splashes of creamy-white, pale yellow, or lime running through the otherwise grey-green, banded foliage. Each leaf is unique, making every plant a one-of-a-kind living sculpture.

Compact and slow-growing, ‘Boncel Variegata’ usually reaches 15–25 cm tall, occasionally taller with age. It produces offsets (pups) from the base over time, forming decorative clumps that enhance its bold, sculptural presence.

Sansevieria ‘Boncel Variegata’ – Care Guide

Light

Thrives in bright, indirect light to bring out the best variegation. Tolerates medium and even low light but with slower growth and reduced variegation. Avoid prolonged direct sun, which may scorch pale sections.

Watering

Extremely drought tolerant. Water sparingly, allowing soil to dry fully between waterings. In summer, water every 2–3 weeks; in winter, once a month or less. Overwatering is the most common cause of failure.

Temperature and Humidity

• Temperature: Prefers warmth, 18–28°C. Avoid temperatures below 10°C.

• Humidity: Perfectly adapted to dry indoor air. Thrives in centrally heated homes.

Soil and Potting

Plant in a gritty, free-draining cactus or succulent compost. Shallow pots suit its rosette form. Repot every 2–3 years in spring, dividing offsets if desired.

Feeding

Apply a diluted cactus or succulent fertiliser once a month during spring and summer. No feeding is necessary in autumn or winter.

Pruning and Maintenance

Minimal care required. Remove old or damaged leaves at the base. Wipe foliage with a damp cloth to enhance its glossy appearance and highlight variegation.

Growth and Maturity

A very slow-growing Sansevieria. Mature plants remain compact (15–25 cm) but gradually produce offsets, forming striking clumps. Occasionally, it may produce flower spikes of fragrant, creamy-white blossoms.

Common Issues

• Yellow/mushy leaves: Almost always caused by overwatering.

• Wrinkled foliage: A sign of prolonged drought – water thoroughly, then allow to dry again.

• Pests: Rare, but mealybugs or spider mites may appear.

Background and Benefits

Sansevierias are celebrated for their durability and striking forms. The ‘Boncel Variegata’ cultivar is particularly prized for its unique starfish-like rosettes and creamy marbling. In addition to its ornamental value, like other Sansevierias, it also filters indoor air pollutants and produces oxygen at night, contributing to a healthier home environment.
