Herbaceous (P. lactiflora)

Indiana State Flower - Peony

Most peonies available in garden centers or nurseries are hybrids of two major classes--herbaceous peonies or tree peonies. Just what are their primary differences?

They are mostly natives to Asia Minor and Europe. Almost all herbaceous peonies are descendants of a Chinese species known as P. lactiflora. These hybrids reach 2 to 3 feet in height, having dark green divided leaves that are shiny and very showy. Peony foliage is bold and striking, even in the fall when it usually embraces the reddish colors of autumn.

Herbaceous peonies typically bloom in late spring, boasting exotic 3 to 6 inch heavily scented blossoms. The blossoms are ordinarily very fragrant and may be single, double or anemone form (with broad, outer petals and a pincushion-like mound of central petals or flowers - modified stamens). Herbaceous peonies thrive in USDA Zones 3 to 8, and bloom profusely after a period of cold winter chill.

Tree Peony (P. suffruticosa)

These are cultivars of P. suffruticosa and are natives to Japan and China. and descendants of P. suffruticosa, a Chinese shrub. This variety is an open, somewhat woody deciduous shrub that can reach 6 feet in height. As with herbaceous peonies, tree peonies are long-lived and resent being transplanted, so you should choose their locations with care. Tree peonies are also more hardy to cold than their herbaceous relatives. The blossoms of tree peonies vary both in size and color, depending on their individual variety. P. suffruticosa is the main Tree Peony. It bears large, single or double white flowers blotched with crimson in May and June.
