Concerns are growing over the continued march of the invasive plant giant hogweed towards Perth.

A Perthshire resident contacted the PA this week pointing out that the dangerous non-native weed, the sap from which can burn the skin, is now visible on the outskirts of the city.

Giant Hogweed, native to the Caucasus of south east Europe, was introduced to Britain as an ornamental plant in the 19th century and spread.

Some plants can grow up to five metres in height and produce up to 80,000 seeds.

The Carse of Gowrie resident told the PA: “For several years I have raised this subject with PKC and rail and roads authorities.

“This dangerous, invasive, weed has spread from the A90 at the old level crossing before Walnut Grove, down the A90 slip road to Perth, under the Friarton Bridge, and is now present beside the road into Perth.

Under the Friarton bridge it is visible on both sides of the A85.

“Nothing seems to be happening and the problem is getting worse. It requires continuous eradication treatment and monitoring as it comes back every year.

“It is spreading, and if it gets into domestic gardens who knows what will happen.”

A PKC spokesperson said this week: “Where giant hogweed is found on council land, we will take appropriate steps to deal with it as an invasive species.

“The majority of the locations being referred to fall within the remit of the trunk road operator, Amey, and we have flagged the issue with them for attention as soon as possible.

“Members of the public can report Giant Hogweed on Council land to us by calling 01738 475000 or emailing enquiries@pkc.gov.uk.

“The presence of the plant on privately-owned land should be reported to the relevant landowner.”

In 2022, within the PKC council area, there were efforts to tackle giant hogweed and other invasive plant species on the banks of the Allan Water near Greenloaning.

Allan Water Angling Improvement Association (AWAIA) had received a grant of £9238 that year from the Crown Estate to remove hogweed, Japanese knotweed, Himalayan balsalm and American skunk cabbage.

The work, backed by Forth Rivers Trust, involved volunteers, wearing protective clothing, spraying weedkiller.
