Horsenettle - Solanum carolinense Linnaeus
Horsenettle is a common native wildflower in North Carolina, often considered a weed. The flowers and yellow tomato-like fruits are attractive, but the stems and leaves are well armed with prickles and the plant is very difficult to pull up. It is found in disturbed areas from farm fields to lawns.
