Linaria dalmatica is a short-lived, perennial herb that can grow 3.9 ft. (1.2 m) tall. The overall form of the plant is narrow and upright, with multiple stems growing from a single woody base.
Foliage
Leaves are pale green, waxy, and heart-shaped, about 1-3 in. (2.5-7.6 cm) long in length, that clasp the stem at the base.
Flowers
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.
Fruit
Fruits are capsules that are 0.1-0.3 in. (3-7 mm) long. Each capsule contains numerous small, black-brown, ridged seeds.
Ecological Threat
Linaria dalmatica occurs in fields, pastures, roadsides and rangelands. It is native to Europe and was introduced into North America, as an ornamental, in the late 1800s.
