Bistorta officinalis

Bistorta officinalis (synonym Persicaria bistorta), known as bistort, common bistort, European bistort, or meadow bistort, is a species of flowering plant in the dock family Polygonaceae native to Europe and northern and western Asia. [1] Other common names include snakeroot, snake-root, snakeweed, and Easter-ledges.

Description

Bistorta officinalis is an herbaceous perennial growing to 20 to 80 centimetres (8 to 31 in) tall by 90 cm (35 in) wide. It has a thick, twisted rootstock which has probably given it its common name of snakeroot. The foliage is normally basal with a few smaller leaves produced near the lower end of the flowering stems. The leaves usually hairless; the basal ones are longish-oval with long winged stalks and rounded or heart-shaped bases; the upper ones are few and are triangular, tapered and stalkless. There are stipules at their base which are fused into a sheath surrounding the stem. The petioles are broadly winged. The inflorescence is a spike. The plant blooms from late spring into autumn, producing tall, erect, unbranched, and hairless stems ending in single terminal racemes that are club-like spikes, 5–7 cm (2–3 in) long, of rose-pink flowers. [2] The individual flowers are pink with five perianth segments, eight stamens, three fused carpels, and three free styles. The fruit is a glossy black nut. Flowering takes place in June and July. [3] The plant grows in moist soils and under dry conditions goes dormant, losing its foliage until adequate moisture exists again.

Taxonomy

The generic placement of this species was historically in flux, having been placed in Polygonum or Persicaria but is now accepted as Bistorta. [4]

Etymology

The Latin name bistorta, from bis ("twice") + torta ("twisted"), refers to the twisted appearance of the root.

Numerous other vernacular names have been recorded for the species in historical texts, though none is used to any extent. Many of the following refer to the plant's use in making puddings:

  • Adderwort
  • Dragonwort
  • Easter giant
  • Easter ledger
  • Easter ledges
  • Easter magiant
  • Easter man-giant      
  • Gentle dock
  • Great bistort
  • Osterick
  • Oysterloit
  • Passion dock
  • Patience dock [5]       
  • Patient dock
  • Pink pokers
  • Pudding grass
  • Pudding dock
  • Red legs
  • Snakeweed
  • Twice-writhen
  • Water ledges

Distribution and habitat

Bistort is a native of Europe but is often cultivated and has become naturalized in other parts of the world such as in the United States in New England. It is typically found growing in moist meadows, nutrient-rich wooded swamps, forest edges, wetlands, parks, gardens, and disturbed ground. [6]

Cultivation

This species is grown as an ornamental garden plant, especially the form 'Superba' which has larger, more showy flowers, and has gained the Royal Horticultural Society's Award of Garden Merit. [7] It is suitable for use as a marginal or in bog gardens. Bistort has been cultivated as a vegetable, its roots, leaves, and young shoots being steamed or boiled. Many of its occurrences in the wild may be as a garden escape.

Uses

Bistort has been used traditionally for medicinal purposes. The roots are rich in tannic and gallic acids and both these and the leaves have been used to treat wounds. [3]

In Northern England, the plant was used to make a bitter pudding in Lent from a combination of the leaves, oatmeal, egg, and other herbs. It is the principal ingredient of dock pudding or Easter-Ledge pudding. [8] The root of Bistort can be used to produce an astringent that was used in medicine. The roots are also eaten in Russia and northern Asia. [9]

The Polygonaceae are a family of flowering plants known informally as the knotweed family or smartweed—buckwheat family in the United States. The name is based on the genus Polygonum, and was first used by Antoine Laurent de Jussieu in 1789 in his book, Genera Plantarum. The name may refer to the many swollen nodes the stems of some species have, being derived from Greek [poly meaning 'many' and gony meaning 'knee' or 'joint']. Alternatively, it may have a different origin, meaning 'many seeds'.

<i>Persicaria</i> Genus of flowering plants in the knotweed family, Polygonaceae

Persicaria is a genus of herbaceous flowering plants in the knotweed family, Polygonaceae. Plants of the genus are known commonly as knotweeds or smartweeds. It has a cosmopolitan distribution, with species occurring nearly worldwide. The genus was segregated from Polygonum.

<i>Polygonum</i> Genus of flowering plants in the knotweed family Polygonaceae

Polygonum is a genus of about 130 species of flowering plants in the buckwheat and knotweed family Polygonaceae. Common names include knotweed and knotgrass. In the Middle English glossary of herbs Alphita, it was known as ars-smerte. There have been various opinions about how broadly the genus should be defined. For example, buckwheat has sometimes been included in the genus as Polygonum fagopyrum. Former genera such as Polygonella have been subsumed into Polygonum; other genera have been split off.

<i>Bistorta vivipara</i> Species of flowering plant in the family Polygonaceae

Bistorta vivipara is a perennial herbaceous flowering plant in the knotweed and buckwheat family Polygonaceae, commonly known as alpine bistort. Scientific synonyms include Bistorta vivipara and Polygonum viviparum. It is common all over the high Arctic through Europe, North America, incl. Greenland, and temperate and tropical Asia. Its range stretches further south in high mountainous areas such as the Alps, Carpathians, Pyrenees, Caucasus, Alaska and the Tibetan Plateau.

Rumex obtusifolius, commonly known as bitter dock, broad-leaved dock, bluntleaf dock, dock leaf, dockens or butter dock, is a perennial plant in the family Polygonaceae. It is native to Europe, but is found on all temperate continents. It is a highly invasive species in some zones, resulting from its abundant seed dispersal, adaptability to reproduce, aggressive roots, ability to tolerate extreme climates, and hardiness.
