This snapdragon has been called 'wild snapdragon' or 'butter and eggs'. It is a stout plant up to 1.2 meters tall. There are large yellow flowers on the ends of the stems. These flowers have a prominent spur projecting from the back of the petals.

Related species: Yellow toadflax looks very similar but is generaly smaller and has leaves that are narrow an lance-shapped that do not clasp the stem (like in dalmation toadflax).

Interesting facts

Dalmation toadflax is an invader native to the mediteranean region. Today it is mainly a problem in the northern and western states of the US. Toadflax had been used for centuries as a folk remedy and a dye.

Biological Control

A few different types of biocontrol have been used on both dalmation toadflax and yellow toadflax including a defoliating moth (Calophasia lunula), an ovary-feeding beetle, and two seed capsule-feeding weevils (Gymnaetron antirrhini and Gymnaetron netum).
