Dalmatian Toadflax

DALMATIAN TOADFLAX

Linaria genistifolia

Background: Dalmatian toadflax was brought to the United States from Europe, probably for ornatmental purposes. It prefers rangeland and roadside habitat with sandy soils. It is very aggressive and hard to control due to deep roots and a thick waxy leaf cuticle. It reporduces by seed and rootstock.

Description: This perennial weed grows from two to nearly four feet tall. Multiple stems may come from the base. Blue-green leaves line the stem in alternate fashion. Leaves are wedge shaped, have a thick waxy cuticle, and partially clasp the stem. Flowers are yellow and may have white highlights, and have long tails appearing similar to snap dragon flowers. Bloom is in late spring to summer. Fruits are two-celled berry-like capsules containing many seeds.

Control: Biocontrol is available and offers fair control. Select herbicides can offer good control when applied from spring through fall. Contact your local state or county weed specialist for specific updated infromation.
