    The First International Cherry Blossom Prediction Competition ended on February 28, 2022. Students, researchers, and citizen scientists competed to predict the peak bloom date of cherry trees at four locations around the world: Washington D.C., USA; Kyoto, Japan; Vancouver, Canada; and Liestal-Weideli, Switzerland. Vancouver selected for its location the 'Akebono' trees in Maple Grove Park, at the corner of SW Marine Drive and Yew Street. Douglas Justice, Associate Director, Horticulture & Collections at UBC Botanical Garden, agreed to determine the blooming date for these trees and has been photographing them beginning on March 10. With hardly an data to go on for our location, the contestants came up with April 2 as the peak bloom date (70% open) this year for our location's trees.

    I will collect the set of photos here. You can see photos of the trees in bloom in previous years in the Kerrisdale | UBC Botanical Garden Forums thread. Photos from last year are in posting #167 in that thread.

    So far (until March 18) there has been barely any discernable colour. Here is the first photo, taken March 10.

    These are in date order, March 15 to 18.

    In warmer areas of Vancouver, this cultivar is much more advanced, flowers lightened up and puffy, some flowers already open. But temperatures are supposed to reach and stay at 15C degrees next week, so that should advance the flowering here in Kerrisdale quite a bit.

    I swung by the park last evening, March 24. I'm glad I'm not calling the peak bloom date on this. The tree to the right is ahead of the others, at least on the branch closest to the road.

    Here are Douglas's photos from March 25, In the third photo, can see the branch where I photographed the flowers above, at the right side over the black car - clearly ahead of the other blossoms.

    I don't know if this link will work for people, a Vancouver Sun article interviewing Douglas Justice:
    Project open to all aims to predict cherry blossoms

    UBC asks global citizen scientists to predict cherry blossom seasons - Vancouver Sun (2022-03-31)
    They let me copy this. Am I allowed to post it?
