Bur Buttercup, an invasive flowering plant that produces clusters of sharp, spiny burs, is growing aggressively in Southern Idaho including the City of Twin Falls. The plant’s burs get caught in shoes, bicycle tires, clothing as well as animals’ paws and hooves.
Buttercup often grows along roadways, vacant fields, and on unattended properties, but it impacts a far larger area than where it simply grows. After the plant flowers, it’s spiny burs attach to people and animals passing by, or are blown by the wind onto adjacent property. In smaller animals, the burs can cause sores and blisters on feet and legs.
Burs that are not destroyed will sprout new plants in late-winter or early spring.
“This is a quality of life issue for our residents because the plant grows aggressively and it doesn’t respect property lines,” said Sean Standley, City of Twin Falls Code Enforcement Officer. “Often times, we’re made aware of the problem by a resident whose landscaping is overwhelmed by Bur Buttercup that has spread from a neighboring yard or property.”
Many herbicides found in landscape and home improvement stores will eliminate or control Bur Buttercup, but timing is important and it should be applied early in the season.
City of Twin Falls Code Enforcement is educating home and property owners about the need to remove Bur Buttercup. And residents can do their part by inspecting their property from the center of the street to the backyard property line for Bur Buttercup. Residents who are contacted regarding Bur Buttercup have up to 10 days to address the issue.
“Our first priority is to work with citizens and educate them about Bur Buttercup and ways to remove it,” Standley said.
