    Customer photo review of Cosmos Seeds - Purity

    Great germination, grew fast, no complaints! The flowers have a little pink in them, which even though I didn't expect that, I think the color actually goes better than pure white with my other cutting garden flowers. Everything I am growing this year is from eden brothers.
