Dalmatian toadflax is a short-lived, perennial herb that can grow 3.9 ft. (1.2 m) tall. Leaves are sessile, alternate, entire, 1.2-2.4 in (3-6 cm) long and bluish-green. Flowering occurs in May-September, when bright yellow, snapdragon-like flowers develop. Flowers, including the spur, are 1.4-2 in. (3.5-5 cm) long and occur in racemes at the apex of the stems. Fruits are capsules that are 0.1-0.3 in. (3-7 mm) long. Each capsule contains numerous small, black-brown, ridged seeds. Dalmatian toadflax is native to Europe and was introduced into North America, as an ornamental, in the late 1800s. Plants occur in fields, pastures, roadsides and rangelands. |
