Answer: Because the soil beneath trees is both dry and shady, you'll want to plant ferns adapted to dry shade. Here are a few suggestions:
BOSTON FERN (Nephrolepis exaltata) Grows to 2 -4ft in height. CINNAMON FERN (Osmunda cinnamomea) Grows to maximum of 5ft. Evergreen large leafed fern with wooly cinnamon brown hairs. Grows in full shade. ROYAL FERN (Osmunda regalis) Grows to maximum of 5ft. Evergreen delicate shaped fronds. Excellent mixed with other ferns as ground cover. Grows in full shade. FISHTAIL FERN (Nephrolepis biserrata) Grows to maximum 4ft. Evergreen ground cover with fish tail shaped fronds. Spreads quickly. Grows in full shade.
These ferns are native to Florida and should grow well in your landscape. Enjoy!
