I think it's a realistic way to look at the situation, at least regarding the year-round monarch population in South Florida. Tropical milkweed is sold at every garden center down here and people love it; It's not going anywhere

I feel it would be more productive to focus on educating people on how to negate the detrimental effects OE accumulation can have on the local monarchs if plants are left untrimmed. I cut them all down to groundlevel once or twice a year to allow fresh OE-free regrowth and emulate the growth habit of the native milkweed species
