The flowers are a little bland looking, I think. And all of mine sprawled badly, whereas the taller "Dazzlers" around them didn't. I don't think I'll do these again.

The flowers are smaller than other cosmos I've seen (only about 2 inches?), but the plants were very floriferous so overall the effect was very pretty. The flower coloring is just gorgeous. My only problem was that they were very tall and top-heavy, and in a bad windstorm they got knocked over. Many of the stems split at the bottom and died. Some survived but remained sprawled on the ground. Other, shorter cosmos growing in the same area were not affected. So these probably need some support.

Every year I grow a different cosmos. This one I grew with Dwarf Sunny Red and they look beautiful together.

Pretty flower, but not nearly as prolific as the Sensations...I was pretty disappointed overall. This year I'm trying Picotee.
