I visited the Florida Panhandle in 2001 and photoed these practical lawn sundews. In the town of Crestview D. capillaris grew in the clearing of a mowed grassy roadside; just like a lawn. In the adjacent overgrown thicket I saw some pitiful Sarracenia purpurea and S. rubra gulfensis, but no sundews. I had info there was previously P. primulaflora around there but I saw none. Just three years later I got word the area would soon become a strip mall. A group of CPers rescued the pitcher plants there.
Here is more from Greg on the Louisiana residence lawn D. brevifolia:
“I recall someone saying that this is common in subdivisions in the south. Perhaps when I was a kid or when my parents were kids, but now it is exceedingly rare… It is now a rare sight to spot pitcher plants along the side of the road, mainly due to roundup. It is easier to spray poison than to cut the grass. When they used to cut the grass beside the interstate, the pitcher plants and other CP's benefited.”
