After years of waiting, and from the wrong seed batch!, blooms of a Paeonia anomala forma alba: the white-flowered form of Paeonia anomala. One bloomed after a fashion last year, but the flower was stunted and damaged by weather and insects, so this year's is really my first. There is again some insect damage to the outer petals, which I don't ever see on normal pink anomala or any other peony for that matter! This is the first day, and the flower I think is not completely open; should get a fully-open photo added soon.
The foliage is lighter green than the species normally has (especially when first emerging), and without the reddish stem that marks most of my other anomala's, but is otherwise within the normal range for size, shape and narrowness of segmentation.
Two known plants (the bud of the second has coloured up but not yet opened) and a couple of others that I think will be white but the buds are still green. Which means that with a bit of skillful paintbrush hand-pollinating a decent seed set should result (if not this year then soon? I have noticed that some peonies do not set seed in their first year of flowering; and there is always the weather issue!)
