Overview

Paeonia 'Many Happy Returns' is a rare reblooming peony in the Paeoniaceae family — a clumping herbaceous perennial growing 24-30 inches (60-75 cm) tall and 24-30 inches (60-75 cm) wide. Soft pink semi-double flowers 4-6 inches (10-15 cm) diameter with visible yellow stamen center. Blooms in two flushes: May-June and August-September — a documented rebloom cycle is rare among herbaceous peonies. The reblooming trait is the cultivar's defining characteristic. Dark green glossy deeply divided compound foliage. Interspecific hybrid bred by Don Hollingsworth (1986) — parentage involves P. lactiflora and other species. Deadheading the first flush is essential to trigger the second flush. The second flush is typically lighter (fewer flowers, smaller blooms) than the first — a trade-off of the reblooming habit. The semi-double flower form is lighter than fully double types and requires less staking. Requires 600+ chill hours below 40°F (4°C) — does not bloom reliably in zones 8b and warmer. Plant with the eyes (buds) no deeper than 2 inches (5 cm) below the soil surface. Three to five years to full bloom production. Moderate fragrance. Bronze foliage in fall before dormancy. Cut flower: vase life 5-7 days. Deer-resistant. Drought-tolerant once established. Mildly toxic to pets (contains paeonol). Zones 3-8. Full sun. Growth rate is slow.

Native Range

Garden hybrid. Interspecific cross bred by Don Hollingsworth (1986). Parentage involves P. lactiflora and other species.

Suggested Uses

Grown in perennial borders (mid-border) spaced 24-30 inches (60-75 cm) from adjacent plants. Reblooming peony — two flushes per season. Cut flower — vase life 5-7 days. Moderate fragrance. Deer-resistant. Mildly toxic to pets. Zones 3-8.

How to Identify

Identified by soft pink semi-double flowers with a visible yellow stamen center that bloom in two flushes (late spring and late summer). The reblooming trait is rare among herbaceous peonies. Separated from fully double types by the visible stamen center. In Paeoniaceae.

Care & Maintenance

Care Guide

Full sun (6-8 hours). Well-drained soil pH 6.0-7.0. Plant eyes no deeper than 2 inches (5 cm). Requires 600+ chill hours — zones 3-8. Spent flowers from the first flush are deadheaded promptly to trigger the rebloom. Semi-double form requires less staking than fully double types. Foliage stays in place until frost. Deer-resistant. Mildly toxic to pets.

Pruning

Spent flowers are removed after the first flush to trigger the second bloom cycle. Foliage stays in place until after the first hard frost (October-November). All stems are cut to ground level after frost. Peony foliage is bagged for disposal rather than composted if botrytis blight is present, since the pathogen survives in compost.
