Mine are Asclepias curassavica. They grow Ok from seed but the plant takes a while to reach a good size. No cool conditions here! I find it much easier/quicker from cuttings. I keep 2 or 3 in pots on a north facing windowsill and just keep cutting the top out every 3 or weeks! The cuttings root in water in about a week and get potted up after 2 weeks! Then 2-3 weeks in a shade frame and then planted out with a shade cover for a week or two while they settle in. I had quite a production line going!
