Paeonia suffruticosa Lilac - Tree Peony

Paeonia suffruticosa Lilac is a shrubby peony with solitary, semi-double, open cup-shaped flowers in a black-spotted lilac-pink colour, adorned with pale yellow stamens. These wide-cupped flowers measure 18 to 25 cm (7 to 10 in) in diameter and bloom from mid-May to mid-June, perched on erect stems. Some consider shrubby peonies as the epitome of refinement.

Growing fairly slowly, this very hardy shrub reaches a height of 1.5-2 m (5-7 ft). The deciduous leaves are composed of nine lanceolate (lance-shaped) leaflets, which are very smooth and initially brownish-green at bud burst before becoming tender green with a bluish reverse.

Originally from Eastern Asia, Paeonia suffruticosa is more delicate than herbaceous varieties; it prefers sheltered locations, especially from cold winds. It grows in partial shade but tolerates non-burning sunlight and thrives in rich, deep, humus-bearing, moist, acidic, and light soil. It does not tolerate limestone and grows poorly in heavy soils.

In the garden, Paeonia suffruticosa Lilac can be used individually against a wall or hedge or in a border, under tall trees, but always sheltered from winds and in well-ventilated and bright areas. Peonies can be paired with other perennials that bloom before or after them, such as grasses, roses, irises, or bellflowers.
