90% of what looks like grass here are actually young S. palmettos. These really do grow in abundance like weeds there. I saw many that were weed-whacked and recovered:
These may be Needles - there was an older mature one upwind of it:
Almost all of what looks like grass in this pic are actually S. palmettos and Needles. BTW, is that a Euonymus or some thornless Holly at the top left? I saw many flavors of this planted at businesses while there. Most had small clusters of green berries:
I wanted to dig up a yet grass-like S. palmetto but I have no space for one indoors and it wouldn't survive in MD outdoors. So I got this $35 S.minor reduced to $20 because it was placed in a 2 gal pot that was 2/3 the height that it should be. The top 1/3 of the root cluster was exposed and dried out which caused the older fronds to yellow. I'm hoping that next summer in MD it will be in better shape. I almost bought a nice 4' one for $70 but it would not fit in our vehicle:
I only saw 2 plantings of S. minor that I was sure of. And one was at a nursery.
