Abstract:
Yellow toadflax (Linaria vulgaris) and Dalmatian toadflax (Linaria
dalmatica) are members of the figwort (Scrophulariaceae) family.
They were introduced into North America as ornamental plants because of their showy, snapdragon-like flowers. Yellow toadflax was brought from Wales in the mid-1800s as a garden flower by Ranstead, a Welsh Quaker who came to Delaware with William Penn. It flourished in his garden and
soon was cultivated in other flower gardens. Dalmatian toadflax is a native of southeastern Europe introduced around 1900.
