1) Part of the Cycad family I think, just not familiar which one, almost looks like a mini palm with a bulbous base but not a Zamia of any sort I don't believe. EDIT: Found by pure chance, it's called Coontie - (Zamia floridana)
2) This is a popular plant down here in South Florida, small purple flowers (can be seen to the left) and bright red seeds. Very pretty ornamental bush:
3) This is a spider-plant type ground cover that spread VERY fast, also puts out a stalk of white flowers in the spring time. Does very well dry areas as well.
All help is very much appreciated
