Tradicantia, also called Spiderwort ranges in color from this pure white through purple. There are no yellows that I know of. It is a reliable perennial in my coastal Maine gardens. It does flop as the flowers pass and then goes dormant, which can be annoying. When it starts to flop, I cut it back to the ground. A fresh flush of leaves will appear in a week or so. The new shoots are edible.
