Yellow toadflax

Linaria vulgaris

About This Species

Yellow toadflax (Common toadflax, Butter-and-eggs) spreads by a creeping root system. It was introduced from its native range of Europe and Asia. It is typically found in cultivated fields, pastures, along roadsides and other disturbed areas throughout BC. Yellow toadflax can out-compete native plants, which negatively affects plant crops, and reduces grass growing in pastures and rangelands. 

How to Identify

Yellow toadflax grows up to 80 cm in height by a creeping root system. 

Flowers are light yellow with an orange spot on its lower lip, like a snapdragon.  

It has long, slim, light green leaves.  

Similar species: Dalmatian toadflax is a similar plant with yellow, snapdragon-like flowers but grows taller, has larger flowers, and heart shaped leaves.
