Distribution and habitat

About 100 separate stations for box huckleberry have been documented in the scientific literature. By the time of Baird's collection in 1845, the West Virginia stations of the plant had been lost to science, and his Pennsylvania colony was the only one known for some time.

 specimens, those of Baird and Canby. (Coville apparently did not locate Kinn's West Virginia specimen, preserved at the Muhlenberg Herbarium.) Upon examination of the New Bloomfield site in 1918, he discovered the entire colony, except for one patch cut off by cultivation, was connected by roots, and that no seedlings were in evidence anywhere around the margins of the colony. Coville concluded that the plant was self-sterile and reproduced by extending rootstocks. After commercial nurserymen removed a truckload of box huckleberry from the New Bloomfield site in 1918, Coville was particularly anxious to preserve the species, as the New Bloomfield site was the only one then thought extant.
