Native to Europe, Yellow toadflax and Dalmatian toadflax can typically be found on roadsides, grasslands and in crop fields. Like many other weeds, toadflaxes have been introduced to North America as decorative plants but they are now having adverse effects. Whilst these weeds may look pretty and provide decorative appeal, they soon escape cultivation and can cause some serious problems. As part of a new CABI Podcast series, CABI experts Dr Hariet Hinz and Dr Ivan Toševski were interviewed from CABI in Switzerland, who explained to us what measures they are taking to control the spread of toadflax.
