I noticed this last year and thought it maybe wasn't Accolade or Somei Yoshino or plum, and now I'm pretty sure it isn't one of those. I don't expect it to be identified, as it's in Stanley Park, where there are several one-of-a-kind cherries. It's nestled in among some other trees just town-side of the heronry across from the Park Board office at the foot of Pendrell. I'm not good at judging height, but not to let that stop me, I'll guess 20-25 feet. The blossoms are Akebono size or a bit smaller, and while the tree isn't exactly in bloom yet, it's considerably ahead of the Akebonos and Somei-Yoshinos in the park, which have no open blossoms and are not showing all that much pink in their buds. I'll slip in another photo of the tree when there are more blossoms.
