Today, late blooming sakura flowers look so nice.
Japanese most famous sakura is someiyoshino, but this is not someiyoshino.
All someiyoshino are grafted from only one strain and they are only one plant.
So all someiyoshino are bloom almost same timing, except of temperature, because they are only one plant.
It is said that all someiyoshino will be blasted at same time.
I don't know until when it will.
