Oh, dear. I hadn't looked at the date of your original post. Sorry. But now I am less convinced and more confused. Here on ATP in the Plant Database there is Butterfly Weed (Asclepias curassavica 'Silky Gold'). Silly me. In my mind it was Tropical Milkweed (Asclepias curassavica 'Silky Gold'). So I am totally confused. And probably confusing everyone else. So I probably won't pursue this any further. Nap time.
But just for y'all, here's the picture I had planned to post. Note the little aphids on it.
