Tradescantia fluminensis basics

Tradescantia fluminensis, also called Green Inch Plant or Small-Leaf Spiderwort, is an herbaceous perennial plant grown for its beautiful green foliage and pretty white flowers. Tradescantia Fluminensis plants are native to tropical South America and are part of the plant genus Tradescantia.

The plant has escaped cultivation in other areas of the world and is considered an invasive plant in some jurisdictions. Tradescantia Fluminensis is known for its extremely quick growth and certainly can seem to grow an inch per day (hence the nickname Green Inch Plant).

The Tradescantia Fluminensis plant is evergreen, so it will stay nicely colored year-round when conditions permit. It is a perennial plant, which means it will continue to grow stronger and larger each year. The plant grows healthy, green leaves that are shaped similarly to hearts, in the sense that they are rounded on the top where it is wider and droop down to a pointed tip at the bottom of each leaf.

Growing Tradescantia fluminensis

Tradescantia Fluminensis plants are commonly seen growing either as ground cover in a yard or in a pot or basket indoors. Because Tradescantia Fluminensis plants grow quickly, they are very popular in indoor hanging baskets because the long trailing stems filled with leaves will fall out of the basket gracefully and grow quickly.

When growing naturally outdoors, Tradescantia Fluminensis will not exceed a height of 3/4 of a foot. While these plants do not grow very tall, their nature is invasive and their growth is rapid. Tradescantia fluminensis can easily spread by a foot or two in width each year.
