WHAT FLORIDA NATIVE PLANT IS BLOOMING TODAY?: BUSHY BLUESTEM (Andropogon spp. likely glomeratus)
Very tall, showy native bunch grass. Leave in place to dry over the winter as food for flocks of birds. The warblers will latch on and sway as they dine.
I cut some to use as a free alternative to cornstalks as Halloween decorations,
