While I was looking at these trees, Eagle and Tina Chiang were doing the same. Following the centuries-old saying from Kobayashi Issa: "There is no stranger under the cherry tree", we had a little chat. It turns out they are members of the Green Club, started by Joseph Lin, who many years ago started a list of cherry blossom locations (we have posted his photo in memory at Cherry Scouts - Vancouver Cherry Blossom Festival (vcbf.ca)). Eagle sent me the outstanding blossom photo here and gave me permission to post it. He and Tina show up my photo.
The four trees of 'Kiku-zakura' are in full bloom on the north side of Turner, just east of Nanaimo, at April 20, 2024—true to the mid-April bloom date in the Ornamental Cherries in Vancouver handbook. The bloom on one tree is more advanced than the others which still have buds opening. One of the others, is gamely putting on a good show, despite carrying on its Prunus avium attachment.
Oh no, I forgot to visit the 'Kiku-zakura' when I was in the neighbourhood. Well, I was overwhelmed by the 'Shiro-fugen' at Callister Park. They are totally open, very white, and just thinking of starting to change to pink, with just bits of fluorescence in some of the flowers. About three blocks away on Oxford at Pentiction is an arch of 'Kanzan' that should be a festival favourite, as it's easy to take in after visiting the park above, and their blooming overlaps.
