BACKGROUND: Dalmatian toadflax was brought to the United States from Europe, probably for ornamental 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 produces by seed and rootstock.
DESCRIPTION: This creeping herbaceous perennial weed grows from 2 to nearly 4 feet tall. Multiple stems may come from the base, Blue-green leaves alternately line the stem. Leaves are wedge shaped, have a thick, waxy cuticle, and partially clasp the stem. Flowers are yellow and may have white highlights and long tails, similar to snap dragon flowers. Bloom is in late spring into 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.
