LoreThis very large genus of perennial garden flowers falls into its the Polemoniceae, which contains roughly 13 genera, most of which are native to America. Genus Phlox was classified by Carolus Linnaeus in the 18th century and named it from the Greek for flame. The genus contains about 50 different species of both annual and perennial flowers. Only one of these is Siberian and the remainder are North American natives. This species was also classified by Linnaeus first as P. setacea, but he later changed it to P. subulata. It is native to sandy soils in thin forested ridges from New York west to Michigan and throughout the Appalachians. It is an old time tradition in the Appalachians to plant this in rough rural lawns and it is found in graveyards throughout the region.
Average Size at MaturityModerate growing; reaches 6 in. tall, forming a dense mat up to 3 ft. wide.
Bloom TimeSpring into Summer
Design IdeasIt's rare to find such a vigorous source of blue in a ground-hugging plant for rock gardens. A notorious dweller on edges of rocky embankments, where it spreads over curbs and short retaining walls, or amidst rocky outcroppings. And ideal cover plant for difficult edges of dry streambeds or rock waterfalls. Enjoys the fast drainage of elevated spots and thrives in the nooks and crannies of dry stone retaining walls. It is equally at home in the front of a traditional flower border or planted along the edges of flagstone walkways.
