Flowering Inch Plant

The Story

Plant Bio

Tradescantia cerinthoides is a trailing herbaceous perennial native to South America, characterized by prostrate stems that root readily at the nodes to form dense, spreading mats. The foliage features grey-green upper leaf surfaces contrasted by distinctly purple, hairy undersides.

This species is distinguished from the highly invasive Tradescantia fluminensis by its pubescent leaves and significantly less aggressive spreading habit. In spring and summer, it produces terminal cymes of small white flowers tipped with pink or purplish-pink, supported by hairy, purple sepals.

Uses & Benefits:

Features striking bi-colored foliage with grey-green tops and hairy purple undersides, making it an excellent trailing plant for hanging baskets.

Functions as a fast-growing, easily propagated groundcover in frost-free climates or a low-maintenance indoor houseplant.

The small spring-to-summer flowers provide a minor nectar source for generalist insect pollinators and visiting hummingbirds.

Planting

How to Grow

Select a site with bright, indirect light or partial shade to prevent leaf scorch while maintaining vibrant foliage color.
Plant in a well-draining, humus-rich loam or standard potting mix with a pH between 6.0 and 7.0.
Water thoroughly when the top inch of soil dries, ensuring the container or bed drains completely to prevent stem and root rot.
Apply a balanced liquid fertilizer sparingly every four to six weeks during the active spring and summer growing seasons.

Pro Tip

Avoid cutting back into old, leafless woody stems where nodes fail to break; instead, prune younger, leggy stems in early spring to stimulate dense, bushy lateral growth.

Keep It Thriving

Care Guide

Do

Allow the soil to dry slightly between waterings to protect the succulent-like stems from rot.
Provide moderate to high humidity levels to keep the foliage lush and prevent tip browning.
Bring outdoor potted plants indoors before the first autumn frost, as the species is highly sensitive to freezing temperatures.

Don't

Do not allow the plant to sit in waterlogged soil or standing water.
Do not fertilize during the dormant winter months when growth naturally slows.
Do not plant in areas exposed to heavy coastal salt spray or high-salinity soils.
