Dear dyzzypxxy ... I just joined NGA and was looking at information on these wonderful plants whose flowers are such a clear yellow. I too, live in Sarasota and have found them growing happily in my yard for years. They seem to prefer the sun and dry conditions of my front yard along the sidewalk here in the downtown neighborhood of Laurel Park. Have never tried to grow them from cuttings but I do collect the seeds, most of which don't appear to be fertile. They seem to prefer to come up between the seams in the sidewalk. Such seems to be the nature of wildflowers.
Hoping for rain ... Have a wonderful day.
