Description

The plants are herbaceous perennials or small shrubs. The stems grow to 50–200 cm tall and have a cluster of basal leaves, with further leaves arranged alternately up the stem. The leaves are pinnate, 5–30 cm long, with 7-25 leaflets, the leaflets with a serrated margin. Young leaves grow from the crown in the center of the plant. The flowers are small, produced in dense clusters 5–20 mm long; each flower has four very small petals, white to red in colour.

Ecology

Sanguisorba minor is a food plant for the larvae of the grizzled skipper (Pyrgus malvae) and the mouse moth (Amphipyra tragopoginis).

Cultivation and uses

Burnets are cultivated as garden plants. Many cultivars have been bred, especially from S. officinalis. S. canadensis is grown for its white flowers on stems that well exceed a meter tall. The plants hybridize easily, producing new mixes.^[2] S. obtusa is valued for its foliage of pink-edged, gray-green leaves.^[3]

Sanguisorba officinalis is used in traditional Chinese medicinal to treat gastrointestinal conditions and bleeding.^[4]

Sanguisorba minor, salad burnet, has similarly been used medicinally in Europe to control bleeding. The leaves have a cucumber flavour and can be eaten in salads, or used fresh or dried and made into a tea.^[5]

Etymology

The Latin genus name Sanguisorba means ‘blood stauncher’. ‘Sanguis’ is a cognate with ‘sanguine’, meaning 'blood'. ‘Sorbeo’ means 'to staunch’. The plant is known to have styptic properties.^[6]
