And so finally I remember the camera again.

Ripe carpels and seeds of Paeonia mlokosewitschii, the Golden Peony. My other plant has shiny black viable seed, vice the bluish ones here, but is otherwise the same.

This species was the first to wow me with the bright, two-tone autumn seed show. I've since learned about the several other equally fall-showy species but mloko continues to impress-- just not quite so stand-outish. You'd think the literature would comment on this feature of the plants...
