'Kanzan', 'Kanzan', as far as the eye can see. These ones are at 39th & Windsor, looking north: Then there's a beautiful planting with 'Kanzan' on one side and Prunus avium on the other at 35th (I think): Then I got a bit artsy:
The single 'Shiro-fugen' tree on the corner south side of E. 18th, west of Knight is spreading out in its bloom at May 6, 2023. All the other cherry trees along the block on E. 18th, westward from Knight, are 'Kanzan' and their petals are falling apart, creating "cherry snow" and barely able to hold a cluster together for their close-up shot (on left side) with the 'Shiro-fugen' on Coronation Cake day.
See that's what I expect from a 'Shiro-fugen' tree. Egan Davis on his Mountain View Cemetery walk talked about how you can distinguish them from 'Kanzan' by the way they stretch out their limbs. Not like the one I mis-identified as 'Ichiyo' for @tknd because its limbs headed upward in a nice "V" shape. Its seems like a smart tree too - knows it had better stretch its limbs along the boulevard instead of out into the street.
