This appears to be Hypericum tetrapetalum (leaves ovate, broadest and the base, and somewhat clasping the stem) instead of H. hypericoides (leaves usually narrowly elliptic to linear, broadest near the middle, tapering to the base and not clasping the stem). Both have four-petaled flowers, but those of H. tetrapetalum and rounded and "full" looking because the petals are broad, and those of H. hypericoides look like a narrow "X" or cross, being narrow and not equally spaced. H. tetrapetalum is common in pine flatwoods habitats, and H. hypericoides is more common in shadier sites such as oak hammocks. Both can persist after clearing, or on roadsides and in diverse yards.

Do you know if it has the same herbal uses as St. Johns Wort ?
