Let's see how far I can get on this before I have to leave in 15 minutes. This is a good time to sort out cherries with single white blossoms, because there are a lot of them in bloom right now. At the edge of Stanley Park and around the golf course, you can see at least a half dozen. These trees are all in the same little glen just north of the heronry outside the Parks Board office at the edge of the Park at Pendrell/Comox. 'Pandora' The tree is does not have the usual beautiful wide goblet shape that this cultivar can take, but you can see the narrowness of the petals, which means that they do not overlap once they're fully open. Sargentii hybrid These trees have a sort-of round, nondescript shape, or worse. Anne Eng, in a neighbourhood posting, pointed out that they almost always have two flowers to an inflorescence, and the stems seem quite thick relative to other cherries. Flowers are very white once they're open. 'Somei-yoshino' These often have three or four flowers to an inflorescence, petals a bit more rounded than some others, so there are nice stars in the centre, and the stems have hairs. Flowers are very white at peak bloom. (Unknown) Well, not totally easy. I thought this was yama-zakura, but the leaves look like they're going to be coarsely or double-serrated like our Sargentii hybrids. This and the one a block away generally have three flowers per inflorescence, though, and the stems don't seem as thick. Here's another that I think is the same, a block away at the foot of Nelson. That's it for now. 'Akebono', 'Umineko', 'Snow Goose' and a couple of others in another posting later.
