A Trailing Commelinaceae Relative

Tradescantia cerinthoides is an evergreen perennial in the Commelinaceae family, grown chiefly as a houseplant for its fleshy foliage and its habit of trailing or clumping as it matures. It produces small three-petalled flowers, often in white or pink tones, intermittently through the year rather than in one set season.

Light, Water, and Feed

Grow this plant in bright filtered light rather than direct sun, which can scorch the leaves, and pot it in peat-free, free-draining compost. While in active growth, water moderately and give a monthly liquid feed, then ease off watering over winter. Given a sheltered spot with an east, south, or west aspect, it is generally an undemanding houseplant, and can also spend summer outdoors in fertile, free-draining soil.

Cuttings or Division

This plant is propagated most often from softwood stem-tip cuttings taken in spring and summer, though some cultivars can also be increased by division or by simple stem tip cuttings.

Foliage, Habit, and Flowers

The species and its cultivars vary from clump-forming with an initially upright habit that soon turns to trailing, to fully trailing growth from the start. Leaves are typically oval and fleshy, with hairy purple-grey to dark purple undersides, and cultivars show striking variation on top: cream and pink stripes in 'Variegata', a bright red stripe that develops in strong light in 'Red Hill', and pale pink to purple leaves banded with green and white in 'Nanouk'. Small white or pink-and-white flowers appear on and off throughout the year across these forms.

Common Pests to Watch

Across its cultivars, this plant may draw aphids, glasshouse red spider mite, and vine weevil, with some forms also noted for susceptibility to mealybugs and thrips. It is otherwise described as generally disease-free.

Skin Irritation and Reversion

Handling the foliage can irritate skin, so gloves and other protective equipment are worth using when working with this plant. The other recurring issue is reversion in variegated forms, where plain green shoots appear and, if not removed, gradually take over from the patterned growth.

Pinching and Deadheading

Regular pinching of the growing tips keeps growth bushy rather than straggly. On variegated cultivars, watch for and remove any shoots that revert to plain green, since left alone these stronger reverted shoots will outcompete the variegated growth. Spent flowered stems can simply be cut away as they fade.
