There's now a lot of enthusiasm for helping out the monarch butterflies. A lot of milkweed is being planted. Almost any species will do, but it surprises me that butterflyweed isn't leading the way.

Historically, butterflyweed has been used to treat a variety of ailments, as have so many poisonous plants.
