This butterfly weed, Asclepias curassavica, is also known as blood flower. Cathy recently bought a few plants in both orange (this one) and all yellow. Sadly, it is not hardy enough for in-ground planting as a perennial here, but it should do well in containers and brighten up the back patio. This one is in a container right outside our kitchen door and looks great against the green backdrop of Rudbekia growing around the patio. I especially like the bi-color nature of this one, although the all-yellow variety is nice, too.
