Botanical: Paeonia tree, suffruticosa 'Renkaku' white
Common: Peony Tree
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 plants 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 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 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.
