Gardeners' Notes:

Negative plantoid On May 11, 2008, plantoid from Castro Valley, CA (Zone 9b) wrote:

buds don't open fully in my area, 9b-10a in Oakland, CA. The partially opened blooms ball up and turn brown. I learned somewhere long ago that this plant requires a lot of heat for the buds to open fully. When the buds did open fully, the flowers were exceptionally pretty, of classic form and a beautiful dark blood red.
