Paeonia Tree (Tree Peony) suffruticosa ‘Shimadaijin’

Tree Peony, ‘Shimadaijin’ is a reddish/purple/maroon blend which just glows in the garden. One of the brightest colors of all tree peonies. Semi-double blossoms of glowing purple-red combination. One of the top-grade tree peonies! The fact that the tree peony is a very long lasting garden perennial is an added benefit.

Paeonia suffruticosa, or Tree Peonies, are loved by everyone who has ever seen them in bloom and they have been prized and carefully cultivated in the Far East for centuries. A deciduous shrub, not a tree, the Tree Peony has woody stems. A mature shrub produces many huge, long-lasting, silken blooms which delight the eye. The showy flowers are 6-10″ across growing on woody stems. The tree is slow growing and best in the partial shade since the flowers tend to fade in full sun. With flowers two to three times as large as regular peonies, the tree peonies also form small “trees”, and in most climates don’t die down to the ground each winter like their herbaceous cousins. Medium green foliage is deeply divided into oval to lance-shaped leaflets and remains attractive throughout the growing season.

General Information +

General Characteristics: Tree Peonies prefer evenly moist, well-drained soil with a pH close to neutral. If your soil is extremely acid, add some lime when planting. Remove deadwood after the plant's leaf out in spring and remove spent flowers. Tree Peonies usually take 2 - 3 years to become established and bloom heavily. In a mild climate, a tree peony will reach a shrub-like size up to about 4-5 feet is several years. In very cold climates, it will attain full height at about only 2-3 feet. But in either case, the form is fine and the plant is handsome throughout the growing season. No pruning is required, except to cut out dead wood or suckers in early spring. If plants become leggy, a moderate pruning in early fall can be done to shape the plant and encourage additional growth on the lower part of the plant. Remove spent flowers after bloom. These long-lived plants usually take several years to establish and are best left undisturbed once planted. Excellent in borders as specimens or in groups. Also effective as accents or 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 plants.

Planting/Care Instructions +

Planting Instructions: May be planted in any well-drained soil. Dig a hole large enough to encompass the roots without bending or circling. Set the plant in the hole so the graft (the area where the roots meet the crown) is about 1" below the soil surface. Cover with soil to the original soil surface and water thoroughly. Tolerant of summer heat. Add compost as needed before planting. Larger shrubs appreciate some shelter from strong winds. This Tree Peony will bloom one or two years after planting. After the plant has blossomed, remove the seeds to promote size of blooms for the following year.

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