Watch Out For These Seedy Invasives This Fall

Many invasive plants go to seed in the fall, which means they’re primed and ready to spread. Himalayan Balsam, Scotch Broom, and Flat Pea have an extra sneaky, explosive dispersal method – when disturbed by wind, animals, people, or equipment, their seeds pods twist and burst, sending the seeds up to several meters away. Then there’s the cunning Common Burdock – it has small burs that easily hook onto clothing and animals, hitching a free ride to a new location.

Watch the video below to see how Scotch Broom seed pods explode when lightly brushed.

This time of year, you can help prevent the spread of these invasives by leaving them be until the seed pods / burs have all fallen off on their own. Disturbing these plants by pulling, cutting, or even just brushing with equipment when they have seeds can mean increased seed dispersal. Ideally, we deal with these invasive plants before they go to seed, which would be in the spring / summer.

Keep an eye out for these sneaky plants, report any sightings, and learn about proper disposal of invasive plant material.
