common toadflax

Also known as Butter and Eggs, Yellow Toadflax, Wild Snapdragon, Brideweed

Common toadflax produces dense clusters of bright yellow blossoms with vivid orange throat spurs, earning it the traditional nickname butter and eggs. Its two-lipped flowers feature hinged petals that only heavy insects like bumblebees can force open to access nectar reserves. Below ground, deep creeping roots spread aggressively, allowing sprawling colonies to establish quickly along disturbed roadsides and sunny fields.
