Bistort

Scientific Name: 
Persicaria bistorta

The spikes of delicate pink flowers of Common Bistort can crowd damp places such as wet meadows or pastures and roadside verges. In bloom from June to August, this pretty flower goes by a different name in the north of England: 'Pudding Dock' (or sometimes 'Passion Dock'). This is because it was commonly used to create a traditional pudding around Eastertime, probably originating as a cleansing, bitter dish for Lent. Nowadays, many local places have their own take on the basic recipe of Common Bistort leaves, nettles, onions, oatmeal and bacon fat.

How to identify: 
Common Bistort displays cylindrical, pink flower spikes in summer; the triangular or heart-shaped leaves appear from spring onwards, and decrease in size up the stem.
Where to find it: 
Grows across the UK, but most common in Wales and the north of England.
How people can help: 

The Wildlife Trusts manage many grassland habitats for the benefit of wildlife - careful grazing with traditional breeds and scrub clearance are just a couple of the ways we ensure a balance of plants and cover in these fragile habitats. By volunteering for your local Trust you can help too, and you'll make new friends and learn new skills along the way.
