Common Bistort - Bistorta officinalis

An erect, perennial with attractive pink flowers, in a tight cylindrical inflorescence. The basal leaves have a long petiole, while the stem leaves are sessile. The upper part of the petiole has a narrow wing of leaf tissue. The plant grows from a stout creeping rhizome, which spreads to create dense patches.

Photos of flowerhead, leaves and general growth form.

Often in damp areas and near to lakes margins, also in meadows and woods.  A more vigorous variety (var. superba) is often grown in gardens and may survive near houses, after being thrown out

May to July.

Perennial

Found throughout Britain, but commonest in the north west of England.

Uncommon in Leicestershire and Rutland but true status is unclear due to garden escapes/throw-outs. 

In the current Checklist (Jeeves, 2011) it is listed as Scarce.  It may have been introduced in some locations.
