Peonies (Paeonia sp.) are beginning to pop. Here are some just beginning to open with bearded iris (Iris germanica). As with other species, this year's bloomtime seems quite late. I could not find any photos of peonies from last year, but cockspur hawthorns which are in bloom now too (see May 26), bloomed on, or about, May 16 last year, so we are about 10-14 days later this year. Oddly, roses seem on time. Why are some flowers blooming late while others seem unaffected by the cool spring?
