Overview

Paeonia 'Madame Calot' is a heritage French peony bred by Miellez in 1856 — nearly 170 years in continuous cultivation, among the older peonies still commercially available. Plants grow 30-36 inches (75-90 cm) tall and wide. Fully double flowers 5-6 inches (13-15 cm) across open palest blush-pink with rose undertones and fade to near ivory-white. The fragrance is the cultivar's defining feature: an exceptionally strong complex sweet scent that ranks consistently among the more powerful peony fragrances. The early bloom timing (among the first lactiflora peonies to flower) combined with the strong fragrance keeps this a valued garden plant despite competition from showier modern cultivars. The soft subtle color and powerful scent recall a French perfumery tradition — the scent serves as the ornament rather than the visual display. The 1856 introduction date places this cultivar in the first generation of French peony breeding, contemporary with the grands crus of Bordeaux wine. Plants from the original era may still be alive. Dark green glossy compound foliage. Same care as all herbaceous peonies. Mildly toxic.
