Vivid flower color. Nice.

Somewhere I have an article or two, one is from appendix of R. Callahan's Satsuki Book that is now out of print on hours of chill required to set flowers and then force bloom for Satsuki. Basically, in autumn, chill until you see buds form, and have met the "magic" number of hours below 46F or 6 C. Then depending on whether it is a Kurume type or early, mid season, or late Satsuki, you have X number weeks to bloom after raising temperature over 60F days and daylength over 12 hours. Bingo, it blooms. Once you know the number of weeks for a specific cultivar, you can count back from the desired date, to know when to pull it out of cold storage.
