Phlox

Phlox, a genus of plants of the natural order Polemoniaceæ, distinguished by a prismatic calyx, salver-shaped corolla, and unequal filaments. The species are pretty numerous, mostly perennial plants with simple leaves, and mostly natives of North America. A number of species are common in British flower-gardens. It has of late become a favourite genus with florists, and many very fine varieties have been produced.
