Butter-and-eggs (Linaria vulgaris)

Linaria vulgaris, commonly referred to as "butter-and-eggs," is a flowering toadflax species originally from Europe and Central Asia. This nickname stems from the flower's distinctive appearance, featuring bright yellow petals with an orange throat, reminiscent of butter and egg yolks. The plant is mildly toxic to livestock if ingested. Its unique, semi-closed flowers require robust pollinators such as bumblebees to facilitate pollination.
