Well, much to no one's surprise, I'm sure, I am the idiot.
Before I went to buy these trees I told my friend I was keen only on JBP... once there, he said he would not sell any of his JBP stock because they were progressing so well for him... and then we looked at his Scots pines in nursery containers... and then we looked at all his other incredible mature and refined pines...
at the end of the afternoon, he dragged out these three trees and said OK, here you go.
I left thinking they were Scots. Recall, I'm new to all this....
Not sure if I can change the thread title... but here we are.
Apologies for the confusion! And thanks Marie and Walter for forcing me to investigate more deeply.
