This Iowa jungle weather had produced some strange Cosmos. They are all 5-6 feet tall. I have them in several spots and they are just starting to bloom. Sorry, the wind blew a plastic bag in there, I should have taken the picture after I took it out..anyway, the Cosmo foliage is particularly pleasing to me. It's so airy and lacy. I made wallpaper out of it. I'd plant these even if they didn't bloom.
