Epilobium tetragonum aka Square Stalked Willowherb

With its straightforward care requirements, Square Stalked Willowherb is a hassle-free plant that anyone can enjoy.

Square Stalked Willowherb’s native range is Europe, including Britain, from Sweden south and east to W. Asia.

Square Stalked Willowherb should be watered regularly, allowing the soil to dry out between waterings.

Square Stalked Willowherb loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Square Stalked Willowherb thrives in bright and direct sunlight. To ensure your plant receives enough light to survive, place it less than one foot from a window. The current weather in your area may affect the placement in your home. For example, if you live in a region that has longer and more intense periods of sunlight, then you may want to place the plant farther away from the window to avoid direct sunlight and reduce the risk of sunburn. Alternatively, if you live in a region with relatively milder temperatures and less intense sunlight, then you may be able to place the plant closer to the window for increased exposure. Ultimately, the current weather in your area should be taken into consideration when determining the best placement for your Rose Bay Willow Herb.

No verified data on the toxicity of this plant exists within Ploi's records. Should you, someone in your family, or your pet ingest plant material with an unknown toxicity level, it is recommended to seek medical advice.

During the wintertime, it is common for Square Stalked Willowherb plants to go dormant and their growth rate may slow down. Therefore, the amount of waterings should be spaced out more.
