WHAT FLORIDA NATIVE PLANT IS BLOOMING TODAY?: FOURPETAL ST. JOHN’S-WORT (Hypericum tetrapetalum)
This is another of the many Hypericum species that are native to Florida. I have 5 or 6 native species which occur naturally in my garden.
Note that the one best knows as a common supplements is an exotic so is NOT native to our state.
