I updated my list of relative plum blossom times on my Google form on the below thread. I have yet to update it to include My European plums, but just last week as I went around I noticed that most of them are now in full blossom. One you mentioned that you have, Mt Royal was in full blossom and you will see how it compares to the natives you are speaking about in this thread. My next update will include Mt Royal and several others like Wild Goose also very late. I grafted LaCresant, S Dakota, Waneta, Lee Red, Brooks Red, Vic Red and several other native hybrids this year which I hope to include for relative reference in my 2025 plum blossom schedule.
