I don't know about apples in Vancouver, but Salt Spring Island apples are out now (end of April) with the Avium sweet cherries, and since hardly any of my friends could tell me which was which, I'm posting this for comparison. The sweet cherries have quite small pure white blossoms lining the stems, so many of the trees seem to have fat white arms sticking out all over. The apple blossoms are more randomly arranged on the tree, and they're larger than cherry blossoms, tinged with pink, with open little circles forming a star in the centre. If the trunks are not totally covered with lichen, you can see that the cherry bark is horizontally striped and the apple bark is not. Denis Laplante took the photos for me.
