Houstonia serpyllifolia ( Anglèis )

fornì da wikipedia EN

Houstonia serpyllifolia, commonly called thymeleaf bluet,[3] creeping bluet, mountain bluet, Appalachian bluet or Michaux's bluets[4] is a species of plant in the coffee family (Rubiaceae). It is native to the eastern United States, where it is found in the central and southern Appalachian Mountains.[5] It has been documented in the states of Pennsylvania, Maryland, West Virginia, western Virginia, North Carolina, South Carolina, Kentucky, Tennessee, Ohio, and northeastern Georgia.[1][6]

Houstonia serpyllifolia is a low creeping perennial. It produces solitary, terminal blue flowers in spring and early summer.[7] It typically grows in moist areas, and is found habitats such as streambanks, mesic woods, grassy balds, seepy rock outcrops, and spray cliffs.[5]

The specific epithet "serpyllifolia" alludes to the resemblance between this plant and the culinary herb wild thyme, Thymus serpyllum.[8]
