Peonies The red shoots of peonies emerging from the ground has signaled spring for generations of gardeners. Most peonies have unforgettable fragrance, are unexcelled for cutting and may live 20–30 years or longer.

The modern hybrid peony came to Europe in the 6th century as a remedy for epilepsy. Paeonia lactiflora or Chinese peony came to British shores from its native lands of Siberia, Mongolia and northern China.

Peony Facts All peonies range in height from two to six feet, depending on the variety. Types of peonies are Paeonia lactiflora – Chinese peony, an herbaceous perennial and the parent of many of our present-day peony hybrids; Paeonia officinalis – common peony; Paeonia tenuifolia – fernleaf peony; Paeonia suffruticosa – Chinese tree peony. All peonies need a winter season of cold to stimulate flower production in the spring. Peony blossoms are classified as single – a unique form with one or more rows of true petals and a center of bright yellow stamens; Japanese/anemone – five or more outer guard petals and a center of stamens that produce no pollen; semi-double – full flower with prominent tuft of center stamens, sometimes with petals intermixed; bomb – outer guard petals surround a densely petalled pom-pom tuft; or double – large full blooms are all petals with stamens not usually visible. Care of Herbaceous Peonies These plants are the easiest low maintenance perennials to have in your garden. When the red shoots come up in the spring, peony hoops should be installed over the plants but not pushed too deeply into the ground. Once all shoots are up, three inches of mulch may be applied around the plants to retain moisture and keep soil temperatures even. The first year after planting, the peony may be about six inches high with few stems. It probably will not bloom the first year because it is developing a root system. In the second year the stems usually double and growth is taller with blooms nearer normal. By the third year the plant doubles again and the blooms are normal in every way.
