fourpetal St. John's-wort, Hypericum tetrapetalum

Fourpetal St. John's-wort is a shrubby species in southeastern flatlands, particularly pinelands. It is a beautiful species that seems to have gotten lost in the crowd. There are many species of Hypericum, and a number of them have four petals. Many have been used medicinally. But the only reference to any kind of use of this species that I have found is in green roof plantings. And even then it is lumped together with other Hypericum. Fourpetal grows in AL, FL, GA and western Cuba. Flagler Co FL, 1/28/13. St. John's-wort family, Hypericaceae.
