Nice result.

I also have a Yoshino in my back garden. That one was the "colt" grafting stock for the now defunct morello cherry that resided on top.

It also has the classic pale pink flowers & "black forest gateaux" floral scent (apparently almonds) in the hot sun.

My Yoshino flower season is usually march 20 to early April with a late 2nd flush in early may.

No cherries from the "colt" yoshino, but lots of attempts. It is however a perfect pollen partner for a "yoshino spring hybrid by name of "Pandora" which is half the size & has much better autumn leaf colour (flowers early April). "Pandora" pollinated by "colt" produces lots of little black somewhat tateless cherries that blackbirds absolutely adore in late June.

Have a nice day: Ag
