Due to the potential health hazards posed by Giant Hogweed, Stirling Council always acts quickly on any reported sighting on Council land.

Our Land Services and Fisheries Teams regularly assess and treat areas of concern across the local authority area.

If the plant is growing on private land, however, it is the responsibility of the landowner.

We would advise the public to be extremely careful around Giant Hogweed. Please DO NOT touch the plant. Report any sightings on Council land to us via our online form or by calling 01786 404040.

See below for some key FAQs on Giant Hogweed:

Giant Hogweed has long, green stems which branch out into clusters of small white flowers. It is therefore sometimes confused with the common hogweed, cow parsley, elderflower or bishop’s lace. However, it is set apart by its purple-hued stem, thin spines and leaf stalks covered in spots. The plants can grow up to 3.5m (11.5ft) high and can span around 1m (3.5ft). The flower heads can be as large as 60cm (2ft) across.
Please download this leaflet from Scottish Invasive Species Initiative for more information on how to identify Giant Hogweed. More information is also available on the GB non-native species secretariat website.

Giant hogweed is invasive and potentially harmful. Chemicals in the sap can cause phytophotodermatitis or photosensitivity, where the skin becomes very sensitive to sunlight and may suffer blistering, pigmentation and long-lasting scars.

The NHS advises that if you touch Giant Hogweed, cover the affected area, and wash it with soap and water. If you feel unwell after contact with the plant, contact your doctor.

Be extremely careful around the plant. Do not touch it. Report it to us via our online form or by calling 01786 404040.
