Tradescantia spathacea Sw.

Common Name: Moses-in-the-cradle, Boat Lily, Oyster Plant, Cradle Lily
Boat lily is a clumping, broadleaf evergreen, herbaceous perennial houseplant in the spiderwort family (Commelinaceae). Its native range is southern Mexico to Guatemala. It grows 6 inches to 1 foot tall and 1 to 2 feet wide. It was formerly known as Rhoeo spathacea and is still found listed under that name. Plant boat lily in well-drained potting media and give it plenty of bright indirect light. When the plant does not receive enough light it may stretch out and become more lanky or its purple leaves may revert back to green. If kept outdoors in the summer, provide it with afternoon shade. Allow the top 1 to 2 inches of soil to dry out between waterings and cut back on water during the winter.
