  • Posted by ILPARW (southeast Pennsylvania - Zone 6b) on Mar 1, 2021 1:47 PM concerning plant:
    So far, I have only seen this uncommon species in a naturalistic display at the Philadelphia Flower Show in March of 2012 and a planting at Jenkins Arboretum in Berwyn in southeast Pennsylvania in June 2018. It is a low-growing evergreen shrub that spreads rhizomes and forms a colony in time, often a solid mat or a dense broad mound. The thick, dark, glossy leaves, about 1/2 to 1 inch long, develop a reddish-purple tinge in winter. The white or white with pink marks urn-shaped flowers about 1/4 inch long are borne in short clusters (racemes) at the end of shoots in May into early June. The bluish berry-like drupe fruit, like a Blueberry fruit, except with a bigger seed, matures in July-August. It likes part-shade and a soil that is acid, loose, well-drained, yet moist with organic matter. It is native from Pennsylvania through West Virginia & Maryland to Virginia to Kentucky & Tennessee with a new colony found near Durham, NC. I've never seen it sold by conventional nurseries, but it is offered by some native plant and mail-order nurseries in containers. The big mail order nursery of Spring Hill offers a clone called 'Berried Treasure.' It is a lovely broadleaf evergreen. I hope to someday visit a site in central PA near Amity-Hall where there used to be about 300 acres covered by this species, though expansion of a large road took out much of it. There is also a 10 acre Hoverter & Scholl Box Huckleberry Natural Area just south east of New Bloomfield, PA, just west of the Susquehanna River in Perry County that is full of colonies of this species.
