It's a good colorful garden this week because TPP's tree peonies and the fern-leafed peony are all in flower. TPP has blogged about his tree peonies before (here, here, here, here) and the fern-leafed peony too (here and here), and it would not bother him to do another as he isn't tired of them or proud. But lurking in a shady area are several less gaudy peonies that are native to forest communities (Paeonia japonica) so they are shade-loving herbaceous perennials and they grow rather like a trillium and are in that size range. They were slow to establish but now seem to be quite tough and some seedlings are showing up even though it usually takes two years for the seeds to germinate. The flowers are 2-3 inches in diameter and white; growing above a colony of wild ginger they are utterly charming.
