Birdbill Dayflower
Commelina dianthifolia
Birdbill dayflower is a Southwestern perennial with grassy leaves and vivid deep-blue three-petaled flowers that open fresh each morning after summer rains, a charming, drought-tolerant native for sunny gardens. The starchy tubers of a very close relative are cooked and eaten, likely true of this species too.
