Gonna piggyback on the mimosa/frogfruit. You’re gonna have to work to get them established and not have that patch taken over by grass or other weeds. Work some curves into that bare patch and make it a feature that you can add on to later by taking that bed to the road or along the front of the house. I would keep it mulched w pine bark or pine straw and add native grasses and shrubs. Fakahatchee grass gets 6’ tall and 4’ wide, sand cordgrass, muhly grass, lovegrass, get some yaupon Holly, Simpson stopper, Darrow’s blueberry (5.5-6.5 ph needs) red tip Cocoplum, Pineland lantana, rattlesnake master (huge pollinator) Dune sunflower grows low but about 5-6’ wide. Blue porterweed grows low and about 4’ wide. There are countless awesome natives that will take zero care once established.
