Yes, and it should be illegal to sell milkweeds that are loaded up with long-lasting systemic pesticides! Some people go down to the big-box or other nursery and get a bunch of milkweeds ready to plant. It's so sad when people want to help the butterflies and the growers make sure the caterpillars will die if they eat those plants. DD has A. curassavica growing that have been in her yard so long they're bound to be safe by now even if they weren't before...but that's in Houston, where it seldom freezes.
