Paeonia mollis is a very vigorous, free-flowering species, which can grow to a height of approximately 45 cm (18 in.). It has glabrous or softly hairy stems, with bluish green, biternate kleaves, divided into many sessile leaflets with decurrent edges. The leaves are glabrous and often glaucous above, paler beneath with a covering of long white hairs.
In late spring it produces masses of bright magenta or more rarely white flowers, borne on short stems. There are 2-3 densely white tomentous carpels, surrounded by numerous yellow anthers with yellow or red filaments. It is very easy to grow and may be a hybrid between P. officinalis and P. arietina. It appears to be self-fertile and, contrary to most published descriptions, produces plenty of seed. It is tetraploid (2N = 20).

The last of the Paeonia officinalis group is an "odd man out," a peony known only in gardens. It was purportedly brought to Great Britain from Russia in the early 19th century but has never been found in the wild.

All the leaflets are incised into a total of approximately twenty-five narrowly elliptic divisions, some of which are deeply lobed. The flowers, which can be either red or white, are about 3 inches across. Tetraploid (20 chromosomes).

The flowers, appearing in late spring on short stems, may be red or white. It is a compact garden plant up to 45 cm (18 in) high with blue-green leaves.
