I'm voting this the thread most likely to be renamed, but for the moment, that's what we're calling the one tree we know of. If we find others that look like this, they'll be reported here. If we find a better name, we'll rename the thread. West End/Stanley Park: In Stanley Park, at the intersection of the Rhododendron path where it turns the corner away from Ceperley Meadow, across from the concrete bridge over the stream into Lost Lagoon.
Not a timely posting. I'm adding another 'Shujaku' location. One street tree at 20th and Wallace, southwest corner on 20th, reported in the Ornamental Cherries forum, not yet in the Dunbar-Southlands blog for the location where it's growing. See photos.
