Rayners Blueberry is a small trailing or spreading heath found in Atlantic white cedar bogs and seepage slopes and endemic to Lexington County in the Sandhills of South Carolina. It produces few small white flowers in late March to early April and even fewer fruits. The leaves of Rayners blueberry superficially resemble those of the creeping blueberry (V. crassifolium), but can be distinguished by their larger size. Kirkman and Ballington (1990) reduced it to a subspecies V. crassifolium, but Weakley (2002) prefers to retain it as a species because of its distinct morphology. Rayners blueberry was first described in 1980 and is endangered in South Carolina.

Where is Rayner's Blueberry (Vaccinium sempervirens) located in the wild?


Trailing or spreading low-arching sub-shrub with semi-evergreen leaves. (Kirkman et al. 1989)


Slopes along the headwaters of Scouter Creek in Lexington County South Carolina (about 6 miles). Shealey's Pond in Lexington County contains the type specimen. (Kirkman et al. 1989)

  • Seed Collection

The North Carolina Botanical Garden updated seed collections of this rare blueberry in August 2021.  Vaccinium sempervirens is a heavily clonal species known from a single county in SC. It is not known for prolific fruit production and as such most seed collections are small.  To update aging collections and contribute seed to the IMLS longevity project, we collected about 3000 seed from 32 individual clumps (maternal lines) from one population.  This collection is supported by CPC and made possible with the cooperation of the Kieth Bradley and the SC Natural Heritage Program.
