Coltsfoot (Tussilago farfara)
Coltsfoot is native to Eurasia, this includes parts of northern Africa, India, and Nepal. This species is believed to have been introduced to North America by early settlers for its medicinal properties.
One single plant can produce thousands of seeds that have high growth rates which allows them to take over the areas they inhabit. They are often found on roadsides and disturbed areas.
This is an herbaceous perennial plant that visually resembles a common dandelion plant. Its name corresponds to the shape of the leaf which resembles a hoof. It spreads primarily by their underground rhizomes, and it tolerates different soil types and conditions.
Controlling efforts depend on the size of infestation.
Hand pulling efforts are effective with small populations but if roots are left in the soil, they may resprout. It’s important to remove all parts of the plant. It may be easier to remove the whole plants when the soil is moist and make sure to pull the plant before it has grown seeds to reduce the chance of further spread.
Chemical herbicide is most effective to treat large populations of Coltsfoot. This species has been shown to resist commonly used and selective herbicides such as 2,4-D, dicamba, MCPA, and 2-4DB. A foliar application of 2% solution of glyphosate or triclopyr and water plus a non-ionic surfactant is recommended. All herbicides should be applied according to label instructions. Herbicide treatments should be done when the leaves are fully developed in the summer.

Searching for invasive species populations in an effort to detect their presence before their populations become too large to manage is vital to reducing the impacts of invasive species on our natural ecosystems.
