Looking for a beautiful and versatile plant to add to your garden? Consider Linaria vulgaris, also known as Common Toadflax, Yellow Toadflax, or Butter-and-eggs. This species of toadflax is native to most of Europe and northern Asia, as well as the United Kingdom and Spain. It has also been introduced and is now common in North America, though it is considered a noxious weed in some areas. Despite its reputation, Linaria vulgaris has a range of uses. A yellow dye can be obtained from the whole plant or just the flowers. A tea made from the plant is an effective insecticide. Additionally, the plant has been used in folk medicine to treat a variety of ailments. As a perennial plant with short spreading roots, it's perfect for a range of growing conditions and can grow up to 90 cm tall. Its threadlike, glaucous blue-green leaves and pale yellow flowers make for a striking addition to any garden or landscape.
