A Flower Fit for a King

This lovely purplish-blue flower is commonly called King's Mantle. I suppose it's because of the royal coloration of the blooms. Its real name is thunbergia erecta. It's in the same family as Black-eyed Susan vine and Sky Vine, but it is a bush rather than a vine. King's Mantle cannot take frost and dies to the ground in winter, though it usually comes back in zone 8 if given some good mulching in the winter. Try this lovely bush in a container if you live up North.
