Commelina dianthifolia



Add to wishlist Remove from wishlist
A surprisingly hardy tuberous little wildflower from the mountains of the Southwest. This has BLUE flowers of some enviable intensity. The multiple flower buds are held clasped in a pouch like a heart folded in half and one flower emerges each day. This simple bit of wonderment continues on for weeks in June and July. Well after blooming, the pouches now clasping bundles of black seeds continue to hold interest and our sales of this here at the nursery continue strongly even when it is out of flower. Sun, average moisture and decent drainage.
