Toadflaxes (Linaria vulgaris) flower bravely even in sandy, chalky, and otherwise dry soils. These home-grown snapdragons (both belong to the same family, Scrophulariaceae, the figworts) catch the eye in sunny locations with their pretty head of flowers, but can make do with shadier locations too. There they become lanky and the head of flowers is not so dense. Toadflax is pretty in the garden; it grows up in spring in the same place each year and flowers from the middle of summer until the middle of autumn.
