Phemeranthus calcaricusAlso known as:
Phemeranthus calcaricus is a small plant that forms 6" tall clumps. The leaves are tubular, basal, succulent, and only an inch long. The flowers are purple, violet or magenta, five-petaled and star-shaped. They only open in the afternoon, and appear atop slender stems that can vary in height up to 12".
Limestone fameflower is an easy species to grow, and is adapted to adverse conditions. It will thrive in poor, well-drained rocky or sandy soil, and in full sun. It spreads slowly by rhizomes, and more aggressively from seed. This is an ideal rock garden, or container plant that will bloom continuously from spring until fall: April to September. Zones 6-7
Very easy to propagate from seed without pretreatment. Can be propagated by division anytime during the growing season.
Phemeranthus calcaricus is a very rare and endangered species in the wild, native and endemic to only a handful of counties in the southern Appalachians. Though its natural range falls within zones 6 and 7, it seems that is adaptable to a much broader range in cultivation. It is underutilized and under commercialized, though it has recently been found to be a promising species for use on green roofs. It should not be collected in the wild.
