Cobweb Spiderwort or White Velvet are apt monikers for this hairy tradescantia. Leaves and stems are covered in fine white hairs, casting a silvery white sheen over all. In the nursery, we're never quite sure where to put this unique trailer, as it does well as an outdoor sun-loving summer annual, and yet flourishes indoors year-round. Mounding up to 12 inches tall, then trailing over 18 inches wide, the downy green leaves make an interesting contrast to other summer annuals outdoors, and can stand on its own as an indoor specimen. Given the right conditions indoors, Cobweb Spiderwort will produce bright pink flowers at the ends of the stems.
