Tradescantia subacaulis

A low, nearly stemless spiderwort of sandy soils in eastern and central Texas (and Arkansas per the checklist), flowering blue to purple in early spring. It grows through the mild winter and spring, then usually dies back to its fleshy roots during the hot summer. Give it sun, sharp sandy soil and a dry summer rest.
