Ross,
I don't know what your spring was like in Santa Fe but here in Lubbock
we had a late freeze that froze out a lot of our bloom before we even
saw a hint of a bloom stalk. Out of @ 900 cultivars I ended up with
60% bloom. There were quite a few that had frozen bloom stalks that you
could see but many more that were frozed before they got far enough
along to see. Maybe this is the answer to part of your problem. As
Kathy said it is natural and desirable for some of the fans to not
bloom. In fact if they did we would all be in trouble. Hope this
helps.
