  • Global Rank: T1 - Critically Imperiled

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.

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

Ecological Relationships

Found in a unique hillside seepage bog with a canopy of Chamaecyparis thyoides and Pinus serotina and also on some upland clay and sandstone outcroppings dominated by Pinus palustris (Kirkman et al. 1989). It is a poor sexual reproducer and asexual reproduction is by air layering and seems to determine colony size (Kirkman and Ballington 1989).
