Linaria is a genus of about 100 species of herbaceous annuals and perennials that was traditionally placed in the figwort family Scrophulariaceae. Due to new genetic research, it has now been placed in the vastly expanded family Plantaginaceae. The genus is native to temperate regions of Europe, northern Africa and Asia, with the highest species diversity in the Mediterranean region.
The members of this genus are known in English as toadflax, a name shared with several related genera. The scientific name means "resembling Linum" (flax), which the foliage of some species superficially resembles.
Some of the more familiar Linaria include:
- Common toadflax or butter-and-eggs (Linaria vulgaris), a European species which is widely introduced elsewhere and grows as a common weed in some areas.
- Broomleaf toadflax or Dalmatian toadflax (Linaria genistifolia, syn. L. dalmatica), a native of southeast Europe that has become a weed in parts of North America.
- Purple toadflax (Linaria purpurea), a species native to the Mediterranean region grown as a garden plant for its dark purple or pink flowers.
- Pale toadflax (Linaria repens), a species from western Europe similar to L. purpurea, but with paler flowers.
L. vulgaris has been used as a medicinal herb for the treatment of many illnesses and conditions, including cancer, hepatitis, hemorrhoids, scrofula, and scurvy. It has been used as an astringent, an emollient, and a laxative.
