Dalmatian Toadflax

Dalmatian Toadflax
(Linaria dalmatica
or Linaria genistifolia var. dalmatica)

An introduced plant, frequently seen along roadsides. It is native to Eurasia.

The attractive flowers look like spurred yellow snapdragons, growing in the leaf axils of the stiff stalk. The plant was probably introduced as an ornamental, but has escaped and become a very noxious weed because it crowds out native grasses and useful forage plants.

It is often called by the common name "Butter 'n Eggs" because of the combination of dark and light yellow colors in the flower.
