Vigorous perennials grown for their white, pink or blue flowers, each Spiderwort stalk holds many buds which each open only for one day. Flowers bloom all summer. Used as a ground cover, but can be invasive. Good in pots or hanging containers. Shear untidiness to encourage more flowers. Plant in part sun in hot areas and give ample water. Also sold as Tradescantia virginiana, plants are available in spring in containers.
One of the best, with large reddish-magenta flowers.
