Paeonia (Peony) officinalis ‘Rubra Plena’

Rubra Plena’ is a glorious traditional Peony blessed with the deepest, crimson-red, double blossoms that have little rosettes of frilly petals. It has beautifully scented, full and luxurious blooms in the traditional cottage peony way. This is a species known to Europeans since the middle ages; in the U.S. it’s known as the ‘Memorial Day Peony’; one of the essentials carried out west in the covered wagons. An ever-popular peony, spotted quite frequently alongside old farm properties that is very hardy, strong and compact. Very well known, and just as popular today as it ever has been.

The Peony is an extremely long-lived, hardy, shrub-like plant. Once they’re established, they’re as hardy and dependable as oaks, creating a fantastic season of bloom in your yard year after year. The spreading clumps form hedges. Excellent cut flower. Peonies are a standard of the perennial border, both as specimens and in groups. Also effective as accents or herbaceous hedges along fences, sidewalks, driveways or walls. Flowers are extremely showy, and foliage remains attractive throughout the growing season, either alone or as a frame or backdrop for other flowering perennials. Often thought of as a plant used on the farm or out in the country, they bring a little bit of that country feeling to your garden. It is not uncommon to see peonies planted in a mass.

General Information +

Botanical: Paeonia officinalis 'Rubra Plena'

Common: Peony

General Characteristics: This herbaceous (soft stemmed) peony is a shrubby plant that, each year, will typically grow to 3' tall by mid-spring, bloom, display attractive foliage throughout the summer and early fall, and then die to the ground after frost. An old standard that features very large, very fragrant, pink double flowers. Glossy green foliage is divided into oval to lance-shaped leaflets. Each plant will flower for approximately 7-10 days. You can plant other peonies with staggered bloom times to extend the total peony bloom period to approximately 6 weeks during May and June. Remove spent flowers after blooming. Cut foliage to the ground and remove the foliage from the garden in fall after frost. Plants are long-lived, do not need to be divided and can be left undisturbed for years.

Tip: If plants do not flower, possible causes include (1) planted too deep or too shallow, (2) too much shade, (3) late frost killed buds or (4) plant is too young or has been recently moved or disturbed. Large, fully double flowers usually need staking or other support because they tend to arch toward the ground in the best of weather and can be literally driven into the ground by a hard rain. Can be left undisturbed for many years. In severe winter climates, plant with eyes 1-2 inches below surface of soil (then top with winter mulch); Zone 6-7, cover eyes with 1 inch of soil, and mulch lightly for winter; Zone 8 or 9, leave the eyes exposed to allow as much winter chill as possible, do not mulch around eyes. Not suitable for areas where winter temperatures rarely fall below 40 degrees F. or plants will produce plenty of foliage, but be shy about blooming.

Planting/Care Instructions +

Pests or Diseases: Peonies are considered to be relatively pest free. Ants on peony buds are common and totally harmless.

Planting Instructions: Easily grown in rich, fertile, medium wet, well-drained soil in full sun to part shade. Dig a hole large enough to encompass roots without bending or circling. Set the plant in place so the eyes (tender white swellings protruding from the crown area) are about 1 inch below the soil surface. Cover with soil to the original soil surface and water thoroughly. Add compost as needed before planting.
