Dalmatian toadflax is an appealing plant with snap-dragon type flowers that are a vibrant yellow. However, don't let this pretty plant fool you, it is far more aggressive than the snapdragon flowers intended for flower beds! Dalmatian toadflax has clusters of heart-shaped leaves around each stem, and can grow up to 1.2 m tall. It has fast growing horizontal roots and one plant has have any many as 25 flowering stems which makes it difficult to remove. It reproduces by seed - one plant can produce 500 000 seeds that are viable for up to 10 years - and vegetatively from roots.

This plant is toxic to animals, but it is unpalatable and generally not grazed. Dalmatian toadflax forms dense stands that can reduce forage for animals by forcing out grasses and native species.
