Giant hogweed: Plant is a huge hazard to children says gardener

Giant hogweed looks similar to cow parsley and is a close relative of the plant, however, hogweed is both invasive and dangerous to human health.

The plant originates from Southern Russia and Georgia, can grow to be three metres tall and has thick, bristly stems that have purple blotches.

The unpleasant weed also has white flowers that appear in flat-topped clusters, similar to cow parsley.

The plants look impressive when fully grown but it is known as Britain’s most dangerous plant as it can cause serious harm to people who come into contact with it.

The experts at GardeningExpress.co.uk have shared everything Britons need to be aware of when it comes to giant hogweed and what to do if they come into contact with it.

Giant hogweed is not illegal to have on a property but is considered more dangerous as it poses a threat to people.

Chris Bonnett, the founder of GardeningExpress said: “It’s vital that people familiarise themselves with what giant hogweed looks like as the effects of coming into contact with the plant are extremely serious.

“The plant typically grows in damp and moist environments and I urge anyone who spots it to get in contact with their local council or an experienced gardener.

“Trying to handle Hogweed on your own could result in some serious burns and blisters which could require surgery.

“When the sap from the plant comes into contact with the skin, it prevents the skin from protecting itself from the sunlight which can cause a serious burn.

“We’re hoping that by sharing some information on the plant, we can help keep everyone safe from hogweed.”

What Britons need to know about Hogweed:

Why is it so dangerous?

The sap from hogweed is toxic as it contains furanocoumarins which are released as part of the plant’s defence mechanism. These chemicals are what burn the skin and make it sensitive to sunlight.

When the sap comes into contact with the skin, it prevents it from being able to protect itself from the sunlight, making the skin extremely sensitive which can cause severe burning and blistering.

Where does it grow?

Hogweed flowers usually bloom in June and July in open, moist and damp areas. They’re usually found near streams, rivers and in the woods so Britons need to take care when walking and cycling.

Hogweed could also be found in open gardens, roadsides and waste grounds.

What to do if you spot it

The local council needs to be contacted if hogweed is spotted in a public space.

If hogweed is spotted in a garden, call an experienced gardener and avoid touching it.

What if you come into contact with hogweed?

If a person comes into contact with hogweed sap, immediately wash the affected area with some mild soap and cool water and avoid exposing this to any sunlight to minimise damage.

If blisters begin to form, seek medical attention. Some irritation can be treated with steroid creams but more serious reactions could require surgery. If the sap gets into your eyes then see a doctor immediately.
