The Vancouver Parks seem to have no end of unique trees. It would be nice to identify this one because it's part of the Japanese War Memorial site. There's obviously parts of it missing, so it's not clear what the shape would be or how tall it would be. The blossoms are huge, and when it was first coming out, I thought it might be a double Mikuruma-gaeshi, but the petals have none of the pink pin-striping seen on that cultivar. The only other cultivar we know that has blossoms that size is Tai Haku, and I have seen some double blossoms on Tai Haku, but this tree has mostly double blossoms, with only a few singles.
