Here’s a plant I definitely want for the garden:

This is purple milkweed, asclepias pupurascens. It’s an endangered species in Massachusetts. I took this pic in the rare plants area at Garden in the Woods. Although endangered, it looks like it’s possible it get purple milkweed commercially, at least as seed. One day, if I have my way, a bunch of these will replace one of my many stands of orange daylilies.
