Great Willow-Herb, Fireweed, French-Willow
Epilobium angustifolium is a rhizomatous perennial species in the evening primrose family, Onagraceae. Rhizomes are plant stems that are modified to grow horizontally, typically under the soil surface, they possess the ability to grow roots and shoots to form a new plant, even if the connection to the main plant is severed. Thus whole new plants can grow from small rhizome fragments left in the soil. Many species that possess rhizomes are invasive and this is why they are so hard to eradicate. This plant has an upright, spreading habit and can grow to around 1.5m tall and 2.5m wide.
