West Dunbartonshire Council has issued a guide to help residents identify a poisonous plant which can cause skin burns and its smaller harmless relative.

The advice comes after a 10-year-old girl broke out in painful blisters after touching giant hogweed when on a fishing trip with her family at Loch Lomond.

Last week the council warned people to avoid contact with the plant and report sightings of it on council land.

Since the request that sightings be reported, several concerned residents have contacted the council concerned about what they fear is giant hogweed growing in the area.

A West Dunbartonshire Council spokeswoman said: "We’ve received a number of calls from residents concerned that giant hogweed is growing near their home.

"In many cases the plant has turned out to be common hogweed which is much smaller and not harmful to humans.

"Key differences between hogweed and giant hogweed include the height, width of stem, size of leaf, size of flower head and size of seed."

A council has published a guide to help people identify giant hogweed and differentiate it from common hogweed.
