This tree is more upright than Shirofugen, and the blossoms are a little smaller and a lot puffier. The tree is very visible on a private apartment building property on Robson west of Gilford in Vancouver's West End. It's past peak on May 15, but there are a lot of flowers still looking very good. It fits Kuitert's description of Prunus 'Kiku-zakura' (not weeping, so not 'Kiku-shidare-zakura'), except that the undersides of the leaves don't seem very whitish green, the peduncles and pedicels are Shirofugen length (but no hairs, which is consistent), and I don't know what it means to say the "calyx is disk-shaped receptacle, with a depression or hole in the middle". Is that what's shown here? That's supposed to determine if it's 'Kiku-zakura' or not. There were around 100 petals on the flower I examined, and several of the blossoms have the second-story flower. What I first thought were phylloid pistils are sepals (or "leafy sepals") on the upper-story flower and there were accessory sepals on the main flowers.
