I was decidedly less cautious with the Berlandiera seeds you sent me. I scattered them in a small patch of bare dirt in the spring and they bloomed the first year. In my yard they only open and smell wonderful for a few hours each morning. I enjoy pulling weeds a lot more when there's such a wonderful scent wafting through the garden. They all survived last winter without any mulch (it kept blowing away). Last winter was pretty mild and moist though, so we'll see how it fares after this year's cold, dry winter.
I snipped a few chocolate daisy blooms to add to our wedding cake last summer. You can just see them in the middle of the cascade.
