Paeonia brownii is a glaucous, summer hibernating, perennial herbaceous plant of 25–40 cm high with up to ten stems per plant, which grow from a large, fleshy root. Each pinkish stem is somewhat decumbent and has five to eight twice compound or deeply incised, bluish green, hairless, somewhat fleshy leaves which may develop purple-tinged edges when temperatures are low.
The bulbs are produced to satisfy the demand for bulbs for parks, gardens and as house plants, in addition to providing the bulbs necessary for the production of cut flowers. The international trade in cut flowers has a worldwide value of approximately 11,000 million Euros, which gives an idea of the economic importance of this activity.
It is a herbaceous perennial plant growing 23–27 in (58–69 cm) tall, with biternate, glaucous leaves with obovate lobes.

The California peony is most related to, and close in appearance to Brown's peony, with which it constitutes the section Onaepia. Common characters include having rather small drooping flowers, with small petals and a very prominent disk which usually consists of separate segments, while the seeds are cylindrical rather than ovoid.
Paeonia lactiflora was known as the white peony (P. albiflora) when first introduced into Europe. [4] It was brought to England in the mid-18th century, and is the parent of most modern varieties. It has been grown as an ornamental in China since the 7th century. [2] The Latin specific epithet lactiflora means "with milk white flowers". [5]
