Ground covers under Fruit trees in Florida?

[TonyinCC]

Wondering what ground cover plants people have had the most success with in South Florida. I don't have a sprinkler system and have limited amounts of reverse osmosis  water to use.  Mulch seems to either dry out too fast or absorb too much of my precious RO water.
Will doing this stunt the growth of shallow rooted trees like sapodilla?
Mangos don't seem to mind small plants under them but my first thought is I don't think grass is a good idea. I have left a few weeds that might be suitable grow under a few trees.
 Ideally I would like something drought resistant, 6 - 12 inches tall or less, nitrogen fixers would be ideal.
Usable herbs or veggies a bonus.
 Would some type of peas work during the cooler season as an annual?
I have tried perennial peanut recently but rabbits ate it to nubs. Moved the peanut in with larger potted trees out of the reach of rabbits.
Would rather use a living green mulch.

Tony your asking a lot for that cape soil even weeds grass has a hard time (smutgrass ,indian goose grass) kidding aside there was a perennial peanut called waxy leaf that was a deep rhizome that could take bad conditions.
  The gem mango wood is growing yeh!

What about mimosa?

Mimosa sounds almost perfect if I can find some to buy or collect.
Have not seen it at any local nurseries.
I found some online at Florida Nursery Mart but that is a long drive...

Shot, do you know where you can get small amounts of FRESH seed of this waxy leaf type??? i have ordered seeds twice before and just received dried up unviable seed. I would like to try it in southern Ca. around my pineapple

I would share some mimosa strigillosa rooted pieces you would need to pot them immediately and treat as tender cuttings. Otherwise All Native Nursery was carrying them.
