Xeriscape, Florida Friendly and Florida Native are not all the same.

In the new age of being "green" and declaring war against the wastefulness that is a turf lawn, many people use the terms Xeriscape, Florida Friendly and Florida Natives interchangeably. They all have similarities but they are not one in the same. I like to call them the Good, Better and Best approach.
GOOD:
Xeriscaping is the practice of using drought tolerant plants, both native and non native in yard settings with rock lawns, mulch and garden settings in place of grass.  Xeriscaping got its start in the desert Southwest were water has always been and issue and grass is near impossible to grow without draining the Colorado River. While helping to save water and being pleasing to the eye, Xeriscaping is not done with exclusively native species.
BETTER:
Florida friendly is not Florida Native despite what Home Depot or Lowe's might say. Often I will hear an employee say "why yes this is native", when it isn't just because it says "Florida Friendly"on it. Riverview Farms in Riverview, Florida uses this moniker and even prints it on their pots. While these will attract pollinators and save water they are not best solution. Some are actually too "Florida Friendly" and are invasive such as Mexican milkweed and Mexican petunias. Others like lantana actually hybridize with native species of lantana and destroy biodiversity.
BEST:
Native Species of all kinds, from trees to small annuals can be found to create a natural habitat in any type of yard, soil or sun exposure. In addition many native plants are specially adapted to Florida's searing heat and dry conditions. The saying "the right place for the right plant" goes a long way. Some planning and research is needed to make sure the areas you want to use will be able to handle the size, growth pattern and water/soil needs of any given plant.  Remember Florida is very unique in its environment especially when you look at other areas of the world in the same latitudes, most of them are desert or arid mountain areas. Meanwhile Florida being perched between two subtropical bodies of water and a tropical currents that curve around it make our weather unique for this latitude. We have a rainy season and even during our driest months, we don't approach desert-like conditions. For the most part our soils are sandy and nutrient poor. This is primarily due to the fact that through the ages Florida has been beach, island, ocean bottom, beach, island, ocean bottom and solid land several times. This is why you can go fossil hunting in central Florida and find sharks teeth nest to a Mammoth tusk. Sometimes we were at the bottom of the ocean, sometimes we were a grassland. At one time in recent history Florida was almost three times wider than it is today. Where I am located on the coast would have still been a 50 mile hike to the beach several thousand years ago during the last ice age. Plant what has evolved here and the animals, birds and insects that evolved along with the plants will flourish. Planting all those pretty tropical plants from Southeast Asia and the like will not attract wildlife no more than putting out ice cubes will attract polar bears. If the animals didn't evolve with it, they wont live in it or eat it. There are a few exceptions to this rule but they don't put a dent in increasing biodiversity in your yard.
So remember water is precious, turf grass is essentially a lifeless desert that sucks up water and gives you wonderful species of yellowing fungus, chichbugs and mole crickets. Xeriscaping is good, saves water, but doesn't provide the flora needed to attract the most types of natives to your yard.
Florida Friendly is Better, well better than grass, but should not be mistaken for Native Landscaping.
Doing a Florida Native yard will get you the birds, bees, butterflies and the occasional puzzled or ticked off neighbor because your yard isn't a flat wasteland .This type of neighbor can be as interesting to watch as a hummingbird or heavy butterfly traffic especially if you throw in the sandals with the black socks.
