Dalmatian Toadflax (Linaria dalmatica)
Identification
Dalmatian toadflax is a perennial forb introduced from Europe as an ornamental plant for use in gardens. It has escaped the garden and is now rapidly invading dry rangeland from 5,000 to 8,000 feet in elevation. Dalmatian toadflax spreads by rhizomes and it should be immediately controlled if encountered.
Leaves of Dalmatian toadflax are waxy, heart-shaped, and clasp the stem. The stems are from 2 to 4 feet tall. The flowers are bright yellow with an orange throat (snapdragon-like appearance). Fruits are a 2-celled capsule containing hundreds of small seeds.
Dalmatian toadflax is well adapted to arid sites and can spread rapidly once established.
