Dear Readers, back in 2002 Rosebay Willowherb was named as the County Plant of Greater London by the charity Plantlife, and, with its long association with the capital and its familiarity to Londoners, it seems an excellent choice. But it was not always so, for this was once a shy, little-seen plant, its spread a result of two World Wars, aided, as with so many ‘weeds’, by the development of the railways.
‘Beautiful as the plant is in its flowering season, when it is in seed it creates desolation and ugliness over the whole area’.
The plant is native to the whole of the Northern Hemisphere, and in North America it is known as ‘Fireweed’: Rosebay Willowherb is either more tolerant of scorched earth than other plants, or positively prefers it. This was to stand it in good stead during the Second World War, when it colonised the bombsites so successfully that the Londoners christened it ‘Bombweed’.
As is often the way with the Blitz, we now look back on it as a time of good spirits and plucky bulldog tenacity. Londoners are said to have seen this new pink plant, which few of them would have seen previously, as a sign of London rising from the ashes like a phoenix. I wonder if some people were also a little perturbed by this new ‘invader’ however, especially as they were right in the middle of fighting a human one. If anyone remembers these times, or remembers their family talking about them, I would love to know!
While all this bombing and burning was going on, the plant was further distributed, just as Oxford Ragwort and Buddleia were, by the spread of the railways, the seeds being happily blown along and finding the clinker and scree slopes of the embankments most amenable to growth. In fact, when I head down to Dorset this week to visit my family I fully expect my route to be a veritable carnival of past Wednesday Weeds, with all the plants mentioned above in full flower.
- The Cree people of North America used the fibre from the stems as sewing thread
- The Kitasoo people used this same thread to make fishing nets
- The Quinault and Skokomish tribes mixed the white fluffy seed fibre with duck feathers to make blankets, and the people of the Klallam mixed the seed fibre with dog hair to weave cloth.
- The Blackfoot tribe rubbed the flowers on to their mittens and rawhide thongs to waterproof them
- The Tanana tribe used the flowers as a mosquito repellent
- The Thompson tribe regarded the flowering of Rosebay Willowherb as an indication that the deer were fat enough to be hunted, and for the Cree it was a sign that the moose would soon be entering the mating season.
Monofloral (single plant) honey from ‘Fireweed’ is made in Alaska and areas of northwestern Canada, and is considered to be a premium product, slightly spicy and delicious.
In Russia, the flowers are used to make Koporye or Russian tea, which was exported to Western Europe as a competitor to Indian and Chinese tea during the 19th Century. It was fermented and dried in the same way as ‘real’ tea but had the advantage of being caffeine free. However, the East India Company was so threatened by the success of Koporye that they circulated a rumour about the way that the tea was produced, causing the trade to collapse. These days only a small amount of the tea is made, for local consumption.
Like Broad-leaved Willowherb, Rosebay Willowherb is also used in traditional Austrian medicine for urinary complaints of all kinds. In North America, it has been used for everything from boils to cancer. Maybe its rarity in the UK until the last century has restricted its historical medicinal and culinary uses here, but who knows what we will come up with in the future?
Vivienne, fascinating post. I have photos my father took on the bombs sites in London in 1947 / 8 which show this plant but until now I did not know the name. Although black & white, the shape is clearly the same. One is taken where the Barbican now stands and shows St. Paul’s in the background. In the foreground is Rosebay Willowherb looking exactly as your second photo. If you want to include in this post I can e-mail a copy.
Hi Dave, I would love to put the photo in the blog, I’m sure my readers would be fascinated, thank you!

Very interesting post. Another fact is that it also has been important for science. In 1790, the German botanist Christian Konrad Sprengel (1750 –1816) discovered self-pollination whilst investigating this species. He went on to become one of the founders of pollination ecology.
Fascinating, Bagogbeag – I knew about the ‘perfect’ flowers, but not how influential their discovery had been. Thank you!
A lovely “weed” in fact I grow the white variety in my garden it is lovely at dusk when the flowers just stand out in the half light. Thanks for yet another fascinating article!
Thanks, Anne! I rather like the white variety as well – did you notice if the flowers attract moths? Evening Primrose, which is a member of the willowherb family, is a big moth favourite….
Not noticed moths around it but yes evening primrose is great favourite of theirs!
