The color of mature blueberries is highly variable, displaying a spectrum from greenish-white and yellowish to various shades of red, blue, purple, and nearly black. The fruit surface may be either glaucous or glabrous, with glaucousness often correlating with similar traits in the plant’s vegetative parts. Notably, fruits from the South Carolina sandhill region exhibit the highest degree of glaucousness.
In terms of taste, Vaccinium stamineum fruits typically possess some bitterness in their skins, though the balance of bitterness and sweetness can vary widely. Fruits from the South Carolina sandhill region are particularly noted for their palatability, suggesting that regional factors significantly influence taste profiles.
As the fruits ripen, they tend to drop to the ground promptly. Due to the continuous structure of the calyx tube with the pedicel, the pedicel remains attached to the fruit upon dropping. This characteristic can influence how the fruit is harvested and utilized, both in wild and cultivated settings.
In summary, wild Vaccinium species, particularly those found in the southeastern United States, display significant variability in fruit size, color, and taste. The larger fruit sizes, particularly in specific geographic regions, are associated with higher seed counts. These berries' diverse coloration and glaucousness contribute to their unique identification, while regional taste variations highlight the importance of local environmental factors in fruit development.
