Mountain Bluet
Mountain bluet (Centaurea montana) is a perennial herb, often found in British Columbia, with bright blue, daisy-like flowers and a thistle-like appearance.
Common Periwinkle
It spreads rapidly via stems that root where they touch the ground and forms dense mats, inhibiting the growth of native plants.
Field Scabious
Field scabious crowds out forage and pasture plants, reducing food availability for grazing animals. It grows along disturbed roadsides throughout the province. It is an escaped ornamental popular for its pretty flower and ability to attract butterflies from its native range of Europe and Asia.
Common Bugloss
Common bugloss is a hairy, fleshy, plant native to Europe, Western and central Asia. It invades disturbed, sunny areas such as roadsides, pastures, and hay fields, which reduces the yield of these crops.
Chicory
Introduced from Eurasia. Often planted for use as salad greens, and the root is used as a substitute for coffee.
