Encyclopedia Article for dayflower

any member of the genus Commelina (family Commelinaceae), which includes about 100 species of weak-stemmed herbs of wide distribution, only a few of which are of horticultural interest. Commelina coelestis, C. diffusa, and C. erecta are often grown as ground covers because of their sprawling habit and their small blue flowers. Especially in moist shady places, they spread easily by cuttings and seed and by rooting of their prostrate stems. As the common name implies, the flowers fade quickly.
