Valery, I posted on the Florida Gardening Forum and one member suggested
Giant Leather Fern (Acrostichum danaeifolium) for full sun locations.
Our database shows
Cinnamon Fern (Osmunda cinnamomea) for partial to full shade but the Floridata website:
http://www.floridata.com/ref/o... states that with plenty of water it will do well in full sun situations.
When googling I found information for
Royal Fern (Osmunda regalis) that also says if kept wet it will survive full for up to 6 hours daily and the Floridata site:
http://www.floridata.com/ref/o... says with plenty of water it can survive full sun more than the the Cinnamon Fern (Osmunda cinnamomea).
