Hard on the heels of P. tomentosa comes P. mascula, the Male Peony. Some years there is no overlap, but this year there is. Which means getting out the paintbrush to pollinate the yellow Woolly one before the bees mess up the genetics. However, down in the shady woodland bed tomentosa rules alone with mascula not even showing colour yet (that is, not yet to the stage of the background bud in this photo). This is a late afternoon photo, with the flower just closing up as clouds move in.
Many others of the round-lobed leaf species are showing colour in their buds and are not too far from bursting forth either.
