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.
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 reproduces by seed and rootstock.
Flowers are yellow and may have white highlights, and have long tails appearing similar to snap dragon flowers. Bloom is in late spring into summer.
