Have Cosmo White Dancing Dolls/Daydream: Trades only :)
I have 2-3 sets of approximately 15 just-harvested seeds off one of my Cosmos "Dancing Dolls" mix.
The seeds were from a plant that was white with a magenta picoted edge and some blooms had magenta stripe -like markings also on the petals. There are a few seeds of Cosmos "Daydream" mixed in.
Most of my flowers on this same plant were sterile, so it's interesting that these blooms produced seed. Not sure what they'll produce. :)
