Warning that alien plant which smells like rotting flesh spreading across UK
Biosecurity experts are desperately trying to stop a giant plant that smells like rotting flesh from spreading across the UK.
American Skunk Cabbages, a non-native plant, has been spied on the river Tweed, as well as in the Scottish Highlands, the central belt of Scotland, Dumfriesshire and Cumbria.
With bright yellow flowers and shiny broad leaves, the huge plants, which grow vigorously on damp areas such as wetlands and ditches, can grow up to 1.5m high.
With no natural predators, numbers can quickly get out of hand and the plants grow so thick and fast that they choke other aquatic life.
Known in Latin as Lysichiton americanus, the popular ornamental plants will soon be banned.
Emily Iles is a project officer for the Tweed Forum, an umbrella organisation of groups including those with an environmental interest in the area around the River Tweed.
It has been running the Tweed Invasives project for the last 14 years in a bid to educate the public.
She said of the plants: “They’re a very big problem when they get established.
“I used to work on the river Nith and that course is completely smothered.
“They’re ornamental plants, we think they were brought in in the 1800s. They just end up getting transported down the water from seeds.
“They basically shade out other plants because they grow so quickly.
She added: “The flower puts up a bright yellow flag and when it dies back, I think that’s when the pungent smell starts.
“If you’ve got hundreds of them, they can get quite smelly.”
A new EU regulation in December highlighted American Skunk Cabbages as being a matter of “union concern”, meaning a problem to both Scotland and England, and new rules are coming into force to ban them from being sold.
