Wandering Creeper Tradescantia fluminensis

Small-leaf spiderwort or inch plant is an evergreen trailing herbaceous perennial groundcover in the spiderwort or dayflower family (Commelinaceae). It is native to Southeast and Southern Brazil to Northern Argentina. Spiderwort gets its name from the thick, sticky secretion that is present when a stem is cut. This substance becomes thread-like and silky when it hardens, appearing similar to a spider web. The specific epithet, fluminensis, originates from the Latin word flumen, meaning "river." It is thought that this references its native habitat along the January River in Brazil.  

This species prefers bright, indirect sun and moist, well-drained soil or potting mix. It can be grown in full sun, but it needs afternoon protection to prevent leaf scorch. Pinching the stems will make the plant denser and prevent leggy stems. It is easily propagated by stem cuttings. When grown outdoors, it will root at each node and can become invasive. 

The plant usually grows 6 inches tall and about 2 feet wide. The foliage is green, oval, fleshy, and the undersides are purple. The stems will cascade downward, and they are fleshy and hairless. The flowers are tiny 3-petaled, white and only last for one day. In their native habitat the flowers bloom from spring to fall; however, as a houseplant, it rarely flowers. Variegated varieties are available.

In colder climates, it makes a good houseplant and its spreading form makes it attractive in a hanging basket though it will rarely flower. In warm climates alternatives should be considered as it is quite aggressive and tends to smother other native ground covers.

Quick ID Hints:

• Leaves are 2-ranked*, stems are trailing; sheaths closed
• Paired bracts enclose flowers that last 1 day each
• Green leaves with purplish undersides

Insects, Diseases, and Other Plant Problems: Monitor for mealybugs, scale, whiteflies, and spider mites. Root rot can occur from overwatering. Considered an invasive species, noxious weed, or pest plant in many locations. Seriously affected areas include Australia, New Zealand, and the southeastern United States.  Consider planting one of the native spiderworts in the left hand column.  Snails and caterpillars can damage young shoots. 

This species is mildly toxic to pets and humans if ingested. Contact with the plant can cause skin redness and irritation. Wear protective gloves when handling this plant.
