Linaria dalmatica is a herbaceous, short-lived perennial plant native to western Asia and southeastern Europe that has become a weed in other areas.
[3][1][4][5] Linaria dalmatica has unique yellow flowers with an orange center that draw individuals to purchase them to display in their gardens.
The distribution of L. dalmatica to North America can be attributed to use as a fabric dye, folk remedies and as an ornamental plant.
It has fast-growing strong, horizontal roots, and can withstand cold, and is a problem for farms and grasslands in the interior of British Columbia.
[11][12][13] L. dalmatica have adapted to a wide range of conditions and can commonly be found in growing on roadsides, valleys, gravel pits, fields, pastures and overgrazed or deteriorated rangelands to name a few.
The roots of L. dalmatica make it a strong competitor as they can produce long and deep taproots that are able to obtain take control of resources required for growth such as moisture and nutrients.
[4][7][16] Flowers are raceme and are composed of five sepals and five petals (tepals), four pairs of stamens of unequal length and pistils are bicarpellate.
Due the high adaptability of L. dalmatica, they are able to outcompete plants and thus remain present and utilize all the resources required for growth.
Herbicide use as these stages can promote long-term control and have a greater impact on the removal of these plants as energy storage in the roots are at its least.
The release of insects feeding on the leaves and stems of L. dalmatica is an additional way to control the rapid reproduction of this plant and localize it to a certain area.
[7][16] Additional insects that feed on the L. dalmatica and used as a biological control are the Brachypterolus pulicarius, Gymnaetron antirrhini and Rhinusa neta and Mecinus janthinus.
[6][7][14] However, it is proposed that due to quinolizidine alkaloids present within the plant, it will cause acute poisoning and other health effects in animals as it has been displayed in sheep and cattle.
