St. Augustine is medium to dark green and coarse textured, and it has a low, dense growth habit. It grows well
in nearly all soil types and tolerates shade, heat, salt and, to some degree, drought. It does not tolerate waterlogged soils
or extended periods of cold weather. St. Augustine grass is an aggressive species that spreads rapidly by above-ground
growth structures called stolons. If managed properly, St. Augustine grass forms a dense cover that handles light traffic
and competes well with most weeds. St. Augustine grass is the most shade tolerant warm-season turfgrass.”
