Yellow peonies (Paeonia ludlowii) growing in a garden on Claremont Ave.
From Wikipedia:
“The peony is named after Paeon (also spelled Paean), a student of Asclepius, the Greek god of medicine and healing. Asclepius became jealous of his pupil; Zeus saved Paeon from the wrath of Asclepius by turning him into the peony flower”.
