Himalayan balsam
Himalayan balsam is a fast-growing plant from the Himalayas. It spreads easily and is a major problem in Sweden. The species is listed by the EU, which means that landowners are required to control and remove it.
Why is it a problem?
- It crowds out native plants and reduces biodiversity.
- When it dies back in autumn, it leaves bare soil, which increases the risk of erosion.
- It spreads quickly because its seed pods burst and shoot seeds several metres.
How to recognise Himalayan balsam
Height: Up to 2 metres
Flowers: Large pink–purple flowers that resemble small orchids
Stem: Hollow, smooth, and often reddish
Leaves: Serrated, lance-shaped leaves in whorls of three
Seeds: Pods that burst and eject seeds over long distances
What can you do?
- Remove early – Pull up the plants with their roots before they set seed (July–September).
- Remove everything – Make sure to get the entire root so it does not regrow.
- Dispose of correctly – Collect in bags and dispose of as combustible waste – never in compost.
- Check plants and soil – Inspect plants and soil before bringing them home.
- Report sightings – Report findings at invasivaarter.nu.
Himalayan balsam often grows near streams and in damp areas. It flowers from July to September.
