Green Small

What is the name of the dark green shrub with small brown leaf that is fairly common in Central Florida?
I wonder what is the name of the shrub that is common in central Florida (obviously you can find in other areas, too) that has leaves that are green when are new and turn brown as they grow. The leaves are quite small and the plant is usually grown as a shrub rather small. Also, if you happen to know how far to place these plants to grow a nice thick bush, let me know that too. Any other considerations to keep in mind when planting or care for this plant could be useful too.
If you have an image that might help. I'm from central Florida as well, so perhaps I know of the plant. k
