- 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.
- 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.
- 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.
- 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.
