Tradescantia (trad-es-skant-ee-uh) Spiderwort, Commelinaceae Family. Perennials of the American continents, of greatly varying form, appearance, growth habit and hardiness. Tradescantia is adaptable to many types of soil as long as it is moist and well-drained; but prefer moist, acidic, humus soils. To encourage new growth and a second round of bloom, after flowering declines, cut plants all the way back.
This clump-forming perennial is easy to divide in either the spring or in early fall. Seedlings may sprout around the parent plant, but they are easily lifted and moved. Plant Tradscantia in a naturalized area, rock gardens, open woodland gardens, or by a pond or stream.
When stems of spiderworts are cut, a viscous stem secretion is released which becomes thread-like and silky upon hardening (like a spider's web), hence the common name.
Attributes: Border plants, Containers, Mass Planting. Attracts butterflies.
