Cultural Significance
In the Victorian language of flowers, toadflax was said to symbolize presumption, perhaps because of its habit of appearing uninvited in cultivated fields and gardens. Its many common names are a testament to its long relationship with people: "Butter and Eggs" refers to the two shades of yellow in each flower, "Brideweed" to its use in decorating at weddings, and "Hag's Taper" was shared with Common Mullein. The unusual closed-throat flower is a striking example of floral specialization: only bumblebees are large and strong enough to force the palate open and access the nectar, making it an important late-season resource for these key pollinators.Shop Our Floral Collection

Frequently Asked Questions about the Linaria vulgaris
What does Linaria vulgaris symbolize?
Butter and Eggs symbolizes presumption, persistence, and irrepressible cheerfulness. Its habit of appearing in cultivated fields and roadsides uninvited gave it the reputation of presumption in the Victorian language of flowers, while its long blooming season and vigorous nature speak to resilience and optimism.
Why is it called Butter and Eggs?
The common name "Butter and Eggs" describes the two shades of yellow in each flower: a paler yellow on the petals and a deeper orange-yellow on the raised palate, resembling the two colors of butter and egg yolk together.
Is Linaria vulgaris invasive?
Yes, it is listed as invasive or noxious in several US states and Canadian provinces. It spreads both by rhizomatous roots and by seed and can form dense colonies in disturbed habitats. Always check local regulations before planting.
What pollinators does Common Toadflax attract?
The closed-throat flower is specially adapted for bumblebees, which are large and strong enough to force the palate open and access the nectar. It is an important late-season food source for bumblebees in late summer and autumn.
What is the difference between Linaria vulgaris and Linaria maroccana?
Linaria vulgaris is a perennial species native to Eurasia that flowers in yellow and orange and spreads aggressively by rhizomes. Linaria maroccana is a small, non-spreading annual from Morocco that flowers in a wide range of colors and is far better suited to garden cultivation without invasiveness concerns.
