Expert Response
Rainier is listed as a pollinator for your two trees on the OSU chart so Royal Rainier will work the same way.
Royal Rainier is a mid-season bloomer, so pollen should be available when Bing and Royal Anne are flowering.
So, if you’ve got room for the three trees, you’re good. OSU has a variety of orchard articles, some are here. Training and pruning your home orchard, PNW 400 has great information for getting your new tree established.
