Carolina Clover

Trifolium carolinianum (try-FOH-lee-um kair-oh-lin-ee-AN-um)

Family: Fabaceae Native Groundcover

Trifolium carolinianum, or Carolina Clover is a native wildflower that is typically found growing in lawns, along roadsides, in cemeteries and in thin, sandy pine or scrub oak woods. Tiny white/purplish flowers are held above the foliage. They are said to be papilionaceous, resembling a butterfly. It is often confused with White Clover. Although a native of coastal North Carolina, it has not been spotted for an extended period of time. The closest location where it can be seen growing is in South Carolina, near the North Carolina border. Insects, Diseases, or Other Plant Problems: This wildflower self-sows. It can be controlled by deadheading.
