Tropical milkweed can enable monarchs to continue breeding well into fall and winter, causing populations to persist longer in certain areas than they naturally would. Unfortunately, this can foster higher than normal infection rates by a lethal protozoan parasite, Ophryocystis elektroscirrha (OE). We have suggestions for native milkweeds you can plant to support monarchs.
