Gardeners' Notes:

I have grown Cosmos for many years and they are beautiful, colorful, and now amazing! These tough plants have been self seeding and growing back each spring for the last two years in my northern Illinois garden where winters are extreme and temps are very cold! The color combinations that resulted are also amazing in that there are many different stripes of color combinations. I had plants that grew in a crack in the driveway that matured and bloomed beautifully! I would recommend this flower to anyone that enjoys colorful blooms blowing in the breezes!

The blooms are highly variable in their coloration, often showing in one day 20 different combos of white, pink and red. They are on fast side to bloom, in about 60 days. They do not stop blooming! I can not find a problem with them! Will always grow them!
