    I pulled this growth off the rootstock of a Kanzan in the West End and then noticed the blossoms had several staminodes, on what from the back of the flower looks like it would be Prunus avium. Is that so rare, to find staminodes on an Avium? Or was Prunus avium 'Plena' developed from some similar find to that?

    How wide are these flowers?

    They were about 3cm in diameter. I'm going from memory now, as I destroyed them.

    Typical size for P. avium 2.5cm. In addition to being on the big side flowers shown don't appear to me to have the petal shape and flower outline usual for that one. Somebody probably grafted onto an open-pollinated seedling that might involve more than one species. In wild roses extra features in the petals (such as extra petals) may be taken to indicate hybridity.

    I found another one, in Shaughnessy, a totally different neighbourhood from the one yesterday. My size estimate was pretty close. Note that in the second photo, the start of the scale is in the middle of the petal on the left.

    Looks the same, suggesting a clonal rootstock is involved. It may never have been named and described.
