Lots of luck with milkweed. Started the seeds in early January in milk jugs with my winter sowing plants. Had great success with high germination. Planted several varieties. Harvesting seeds from the pods now. Lovely and necessary for the monarchs. Several caterpillars have been on the plants but have disappeared. Don't know if they have gone to rest in their chrysalis or if they were eaten by some other insect.
