Dalmatian Toadflax
Linaria genistifolia ssp. dalmatica



IDENTIFICATION

Provincial Noxious. Perennial.
Dalmatian toadflax is an attractive plant with bright yellow snapdragon-like flowers and pale green heart-shaped leaves clustered around each stem. Mature plants grow to 1.2 m and a single plant can have up to 25 flowering stems. Fast-growing horizontal roots make it an aggressive invader of farms and grasslands.

DAMAGE
Toadflax, which is toxic to animals, competes with native grasses and wildflowers and reduces forage for cattle and wildlife. Poisoning is rare as livestock will generally not eat it.

HABITAT
Toadflax can be found at low to mid-elevation in the BC Interior along roadsides, in gardens, cultivated fields, and other disturbed areas. It will tolerate low temperatures and coarse soil. It occurs throughout the Okanagan, Similkameen, Thompson, East Kootenay, Cariboo, Skeena, and Boundary areas.

SPREAD
Toadflax seed is spread by the wind and by birds and animals. A mature plant annually produces up to five hundred thousand seeds, viable for ten years. New plants are also formed from horizontal roots which can be as long as 3.7 m.
