Swamp sunflowerIt breaks into bloom between late September and late October, filling in the edges of lakes and waterways with a spectacular ribbon of yellow.
Blossoms along a waterway in ImmokaleeWhile Lake Jesup is one of the best places to see their beauty, you’ll find them around all of the marshy edges of the St. Johns River floodplain in Central Florida.
We’ve also seen them in Corkscrew Swamp Sanctuary and along the canals of that region in South Florida, as well as the Fisheating Creek floodplain.
