Epilobium tetragonum aka Square Stalked Willowherb

Epilobium tetragonum, also known as the square stalked willow herb, is a flowering plant that belongs to the Onagraceae family. This erect, perennial herb can grow up to 1.3 meters in height and has several stems. Its pink-purple flowers bloom from January to November. It is found in the wild and can be used locally as a food source. However, it can also be invasive in Central Europe. In Western Australia, it has become naturalized in the Perth and Peel regions. Additionally, the Square-Stemmed Willowherb is a rare houseplant that requires regular watering and direct sunlight. It should be placed less than 1 foot away from a window and grown in well-draining soil with organic fertilizer during the peak growing season.
