Peonies are the most anticipated bloom in the cutting garden. Their season is brief—just two to three weeks in late spring—but the enormous, fragrant blooms are worth the wait. Once established, a peony plant can produce for decades with minimal care.

Varieties

Double types like 'Sarah Bernhardt' (pink), 'Festiva Maxima' (white with red flecks), and 'Kansas' (red) are classic cutting varieties with heavy, fragrant blooms. Single and Japanese forms have fewer petals but a striking open center and often stronger stems. For extended harvest, plant early, mid, and late-season varieties.

Planting

Plant bare root divisions in fall, 6 weeks before the ground freezes. This is critical: the roots need fall establishment. Dig a wide hole, set the root so the eyes (buds) are no more than 2 inches below the soil surface. Planting too deep is the number-one reason peonies fail to bloom. Space plants 3 feet apart. Prepare the site with good soil amendments.

Peonies take 2–3 years to establish and bloom fully. Be patient.

Growing

Peonies need winter chill to bloom, which is why they struggle in zones 9 and warmer. They want full sun, good drainage, and air circulation. Feed in early spring with a balanced fertilizer. Once the heavy buds develop, peony rings or stakes prevent the stems from flopping. Remove spent blooms but leave foliage until fall—it feeds next year's roots.

Harvesting

The famous "marshmallow test": squeeze the bud gently. If it feels like a firm marshmallow, it is ready to cut. If it is hard like a marble, wait. If it is soft and squishy, it is past prime. Cut long stems in the morning. Peonies can be harvested in tight bud and stored dry in a refrigerator for weeks, then opened by placing in warm water—a useful trick to extend their short season.

Vase Life

5–7 days in the vase. Condition in cool water. Remove any foliage below the waterline. The blooms continue to open and expand for the first couple of days.

In Arrangements

Peonies are the ultimate focal flower. A few stems in a simple vase need nothing else. In mixed arrangements, pair with sweet peas, foxglove, and ferns for a romantic spring arrangement. They are the most requested flower for home-grown wedding bouquets.
