I realize that at first glance this is quite a dull looking patch of flowers BUT they're the Central American version of butterfly weed, and we actually have several patches of them for the butterflies (and humming birds, too) -
If you take a close look, you can see this beauty:
We've seen many other species of butterfly sipping nectar plus 5 species of humming birds, unfortunately, as yet, have not been successful at getting a photo of the humming birds....
