Rose Bay Willowherb (Chamaenerion angustifolium)

You can see this wildflower towering above the other flora in the woodland growing up to 1.5m tall with pink to purple flowers arranged in a spike. It can take over large areas by sending out thousands of fluffy seeds and spreading by rhizomes, with underground stems producing horizontal shoots which in time can become willowherb plants.

Fun fact: The colloquial name for this plant is fireweed due to the plant frequently colonising areas that have suffered forest fires due to the seeds ability to lie dormant for years. During the second world war the plant was referred to in some areas as bombweed as it quickly inhabits areas laid bare by bomb blast.
