Wonderful perennials for moist, shaded spots.
Spiderworts are hybridized from a wildflower with the wild form of this unique three-petaled flower usually purple. The foliage is lily-like, forming a clump of glossy green. They naturally grow along streams, so give them plenty of water and some shade. The botanical name tells you the history of this perennial plant. It's called Tradescantia after John Tradescant, a famous English plant explorer who visited North America during the colonial period and "discovered" this native perennial flower.
