Rosebay Willowherb, Chamaenerion angustifolium


The familiar tall, pink flower spikes of Rosebay Willowherb, also known as Fireweed, can often be seen crowding together in thick stands in open spaces, such as woodland clearings, roadside verges, grassland, waste ground and along drystone walls. An amazingly successful coloniser, this edible plant has grown in number from a scarce woodland species, to a readily recognisable plant all over the UK. As another of it's common names, Bombweed, alludes to, this expansion occurred as a result of two World Wars clearing huge areas of forest and burning the ground in both town and countryside - the perfect conditions for this plant to thrive.

Rosebay Willowherb is a tall plant, with magenta flowers rising up a central flower spike at it's summit. It has green, lance-like leaves that are arranged in spiral formation up its stem. It's flowers and leaves are edible, with the young shoots being cooked and eaten like asparagus, or added to salads, along with the flower heads. The flowers and leaves are also the main ingredients of the fermented Russian tea, Koporye. A recipe for this refreshing beverage can be found here.

Fresh Rosebay Willowherb shoots can be cooked and eaten like asparagus. Just the fresh tops should be used.

Rosebay Willowherb Tea, also called Koporye or Ivan Chai, is a wonderful aromatic tea!

It also has large pale-green lance-shaped leaves. This plant is deadly poisonous, containing the toxin digitalis, which can lead to serious gastrointestinal pain and heart failure if ingested.
