Although it may be pretty, there’s a purple flower that is currently invading the city.
In the past month, the City of Prince George has received a number of reports of an invasive plant species known as Mountain Bluet (AKA Perennial Bachelor’s Button).
Mountain Bluet is not native to central BC. Consequently, it has no natural predators or diseases to keep it in check, and it is rapidly spreading in Prince George’s ditches and green spaces.
Unchecked, Mountain Bluet can crowd out native plants and reduce foraging opportunities for livestock.
The city recommends that you do not plant these invasive species in your garden or other greenspaces. When disposing of an invasive plant, it’s also important not to throw these plants into your compost since it is then likely to spread into your lawn and garden - if not your whole neighbourhood.
The city says if you see this plant, pull it up by the roots and dispose of it by putting it into a garbage bag and taking it to the landfill. You may need to go back the following years and pull out additional plants since Mountain Bluet has a long-lived seed bank and may grow back after it is pulled. It is recommended that herbicides are only used when necessary.
Prince George also has current infestations of knotweed, burdock, common tansy, and leafy spurge among others.
Residents are encouraged to visit the Invasive Species of BC website to find a control method that best suits them.
You can learn more about invasive plants on the city’s website.
