Paeonia daurica

Description

Paeonia daurica is a perennial herbaceous plant belonging to the peony family. It has slender carrot-shaped roots, leaves mostly consisting of nine leaflets, with one flower per stem. The flower is subtended by none to two leafy bracts, and has two or three sepals, five to eight petals, and many stamens. The subspecies vary in the colour of the petals (white, light yellow, pink, red), the size and shape of the leaflets, and the hairiness of the leaflets and the carpels. Paeonia daurica can be found from the Balkans to Iran, and the Crimea to Lebanon, with the centre of its distribution in the Caucasus. It is also cultivated as an ornamental. Paeonia daurica is a perennial herbaceous photosynthesising plant, emerging in spring and retreating underground in the autumn. It has slender carrot-shaped roots which are directed downwards. The leaves are alternately set along the stems and have an outline of 5–11½ × 8–17 cm. The lower leaves are usually composed of three sets of three entire or sometimes bifid leaflets, and occasionally there is third order division, resulting in a maximum of nineteen leaflets. The shape of the leaflets is wide to narrowly oval, with the largest width at midlength or towards the tip. The base of the leaflets is more or less wedge-shaped or sometimes rounded, the margin is entire and sometimes wavy, and the tip is rounded or has a smaller or larger sharp tip. The upper surface of the leaf is hairless, while the undersides are hairless or sparsely to densely covered in felty hairs. The hermaphrodite flowers are set individually at the end of the stems and are subtended by none to two leafy bracts. The flower itself consists of two or three green sepals, five to eight petals, that may be white, pale yellow, yellow, yellow with a red blotch at the base or with a reddish margin, pink, red, or purple-red, and many stamens consisting of pale, yellow, pink or purple filaments topped by anthers that contain yellow pollen. At the very centre of each flower are one to five carpels that are glabrous, sparsely to densely covered in felty hairs and almost directly tipped by the stigmas which are mostly curved or S-shaped from above.
