Parents across Greater Manchester are being urged to warn their children about a highly toxic plant that can cause severe blistering burns.
Most prevalent at this time of year, Giant Hogweed – also known by its Latin name Heracleum Mantegazzianum – is a plant that originated in Southern Russia and Georgia, and was introduced to Britain and Europe in the 19th century.
The plant itself can reach over 10ft in height and, according to The Royal Horticultural Society (RHS), “most gardeners will want to eradicate it, as it is potentially invasive and the sap can cause severe skin burns”.
The sap contains a chemical called furocoumarin which makes the skin sensitive to the sun, and can cause bad blistering – which can recur over the span of months, and even years.

How can I spot Giant Hogweed?
If you’re looking to identify this dangerous plant to better inform yourself and your children, then The Woodland Trust outlines the appearance of Giant Hogweed by these characteristics:

Stems: The stems are green with purple blotches and stiff, white hairs and are hollow with ridges and a thick circle of hair at the base of each leaf stalk.
Leaves: The large leaves can measure up to 1.5m wide and 3m long, and are often divided into smaller leaflets. The Woodland Trust compares them to rhubarb leaves, with irregular and jagged edges, with the underside of the leaf being described as hairy.
Flowers: Giant Hogweed flowers appear in June and July, and are small and white and appear in clusters on “umbrella-like heads” that face upwards.
Seeds: The seeds are dry, flattened and an oval shape, almost 1cm long and tan in colour with brown lines.
Regular hogweed leaves are more rounded, whereas Giant Hogweed leaves are more jagged.
It’s important not to confuse Giant Hogweed with cow parsley too, as although they look similar, cow parsley can only grow about three-four feet, and also has smaller florets and broader leaves that are much more rounded than the jagged leaves of Giant Hogweed.

Sightings of Giant Hogweed have been spotted in Greater Manchester in recent weeks.
Community group Bolton NEWT say it’s recently found Giant Hogweed plants in Leverhulme Park, along the rivers Tonge and Croal, and at Moses Gate Country Park.
“We strongly suggest taking a few minutes with your kids to show them these pictures, so that they can safely identify giant hogweed and not panic when you find native hogweed or cow parsley.” a spokesperson for Bolton NEWT.

Similarly, Mini First Aid in High Peak and Tameside has also taken to social media to issue a warning about the plant, saying: “Now is the season for ‘Britain’s most dangerous plant’ and with the lovely weather forecast in a couple of weeks time, this stuff will thrive and spread.”
The group added: “All parents, please warn your children not to touch the plant as the leaves, stems, roots, flowers and seeds all contain this terrible poisonous toxin.
“Any parts of the body that come into contact with the sap of a giant hogweed should be immediately washed with soap and cold water and seek medical advice. Further exposure to sunlight should be avoided for at least 48 hours.”

Fire service urges Greater Manchester public to ‘act responsibly’ as heatwave continues
Emily Sergeant
People across Greater Manchester and beyond are being urged by the fire service to ‘act responsibly’ as the heatwave continues this week.
Greater Manchester Fire and Rescue Service (GMFRS) has issued an urgent plea residents and visitors to take extra care on moorland and in rural areas as part of the annual ‘Be Moor Aware’ campaign – which is aimed at preventing wildfires and reducing the impact they have.
GMFRS has issued the plea alongside its partners at United Utilities, the Royal Society for the Protection of Birds (RSPB), neighbouring fire and rescue services, and local councils.
It comes as Amber Extreme Heat warnings and heat-health alerts have been issued by the Met Office and the UK Health Security Agency (UKHSA) through to Thursday this week – with temperatures widely exceeding 35°C nationwide, and in some areas – particularly on the south coast – potentially even reaching 38°C.
Heatwave conditions in the UK are met when a location records a period of at least three consecutive days with temperature values meeting or exceeding the heatwave temperature threshold for that location.

It does seem, however, that northern parts of the country – especially the North West – are missing most of the extremely hot conditions, with current forecasts indicating peak temperatures of 33°C.
But this doesn’t stop the wildfire risk, and the fire service is warning that prolonged periods of dryness but the countryside in danger.
GMFRS data shows there have been 83 wildfires across Greater Manchester since 2021, including a significant rise in 2025, when 38 incidents were record, and there has already been six wildfires recorded in 2026.
“Wildfires can spread rapidly, especially during warm and dry weather, putting lives, wildlife and property at risk,” explained GMFRS Wildfire Lead, Adrian Taylor.
“Many of these fires are preventable, and we’re asking everyone to take responsibility when visiting our moorland areas. Small actions, such as not using disposable barbecues and taking litter home, can make a huge difference in preventing devastating fires.”
GMFRS added that ‘prevention remains our most effective tool’.
“We’re asking the public to help reduce the risk by acting responsibly when visiting moorland areas,” the statement concluded.

Greater Manchester’s heritage railway issues statement as it’s forced to cancel services this week
Emily Sergeant
Greater Manchester’s iconic heritage railway has been forced to cancel its services this weekend due to the heatwave.
In case you hadn’t heard, Amber Extreme Heat warnings and heat-health alerts have been issued by the Met Office and the UK Health Security Agency (UKHSA) through to Thursday this week – with temperatures widely exceeding 35°C nationwide, and in some areas – particularly on the south coast – potentially even reaching 38°C.
Heatwave conditions in the UK are met when a location records a period of at least three consecutive days with temperature values meeting or exceeding the heatwave temperature threshold for that location.
It does seem, however, that northern parts of the country – especially the North West – are missing most of the extremely hot conditions.
Current forecasts indicate that the peak temperatures for Greater Manchester this week will be tomorrow and Thursday, with highs of 33°C in the city centre.
Despite not reaching the heights of the south, East Lancashire Railway (ELR) has still had to act in advance and has taken the decision to cancel its scheduled services for the next two days as the forecast is ‘too severe’.
Taking to social media to share its decision today, ELR wrote: “Due to the current weather warning for the UK, the decision has been taken to cancel all services on Wednesday 24th and Thursday 25th June 2026, including the afternoon tea and mid-week luncheon dining experiences.
“The welfare of both staff and customers is paramount to the ELR, and we believe that the risk in the extreme heat that has been forecast is too severe to allow for the running of our ordinary services.”
As things stand, ELR says its current plan is to have services resume with the evening dining train on Friday 26 June, but this will still be ‘subject to review’, and further updates on this will be issued later in the week.
