An old French introduction that I just love. The pink flower-in-a-flower flowers are often generously splashed with carmine red. The flowers fade to blush. Unfortunately, over the decades, these old cultivars often get mixed up in commerce and though I try to validate their identity with two sources, I’m afraid I have but one source for Thérèse. Published descriptions are contradictory. Despite the doubt, what I grow under the name of Thérèse is an extremely pretty peony.
