We've seen its lovely pink flower stems...

... and now the 5ft high Rosebay Willowherb, also called Fireweed, is releasing abundant fluffy seeds in an amazing fashion.
Although it can be invasive, the pink flowers provide a pollen and nectar source to a range of insects in the summer months.
This plant got its name because it “takes off like wildfire” on lands that have been scorched by fire. In fact, it is one of the first plants to grow in an area of devastation, bringing healing and renewal to the earth.
The history of fireweed tea goes back to 12th-century Russia. People called it Russian tea, (Ivan Chai), and exported it to England, Denmark, Germany and France. At one point in time, rosebay willowherb was all the rage in Britain.
Unlike every other herbal tea, fireweed tea does not just consist of dried leaves in hot water; the leaves are fermented, just like those in black tea. The result is a tea that tastes very much like black tea, only with no caffeine.
Fireweed tea is high in iron, copper, potassium and calcium. It helps boost the immune system, lowers blood pressure and relieves the symptoms of fever. As it contains a high level of antioxidants, it also helps to burn fat, restores the metabolism, and cleans out toxins and heavy metals. Ivan Chai can also help people quit smoking and can be used in the treatment of alcohol addiction.
The plant has many other uses too.

So where was I?
Oh yes, fluffy white seeds. Apparently one plant can produce up to 80,000 seeds!
So, troublesome weed or something a lot more wonderful?
