Floating Pennywort weed is 'threat' to River Trent
River Trent

Environmentalists say they are alarmed by the appearance of the North American 'Floating Pennywort' in parts of the River Trent in Staffordshire.

The non-native plant can grow at an alarming rate, doubling its wet weight in just three days.

According to the Environment Agency, even a small piece can choke an entire waterway, causing damage to its environment, and wildlife.

It can cost millions of pounds to clear.

This bright green cress-like plant was introduced to aquaria the UK in the 1980s. The latest appearance is possibly due to dumping of aquaria plants.
