I've got about 20 varieties and bloom is spread over more than a month. This year Royal Rainier bloomed in the mid to late period close to Lapins. Given the difference in our chilling regimes my results probably aren't going to help you even if I had better notes.

I have to think you are borderline on chilling. My cultivars that set best at marginal chilling are Rainier, Bing, Lapins, and Sonata. I've heard that Stella is even lower chilling than Lapins but I haven't grown it here.

Things that don't set at all with marginal chilling include Van, Sweetheart, Selah, Skeena, Benton, and Sandra Rose. All of the last five are self fertile but need a lot of chilling, 500-600 Utah hrs, to set even 1% of blossoms.

I'm sorry I can't be of more help.
