WHAT FLORIDA NATIVE PLANT IS BLOOMING TODAY?: YELLOW JESSAMINE; CAROLINA JESSAMINE; EVENING TRUMPETFLOWER (Gelsemium sempervirens)
Gelsemium sempervirens is a pretty vine, but caveats apply since all parts of this plant are poisonous. The sap may cause skin irritation in sensitive individuals. Native alternative to Jasmine. Shown above is a bud just appearing.
