A familiar plant along roadsides in July
The Yellow Toadflax (Linaria vulgaris), perhaps better known as Butter and Eggs, is another wildflower of dry fields, waste places, gravelly areas, and roadsides. It can grow from one to three feet tall. The narrow-leaved plant has snapdragon-like flowers in two shades of yellow. These flowers grow in long spikes. Because the flower is largely closed by the fused petals forming its underlip, the Toadflax needs strong insects to push insde to pollinate it. Bees and Bumblebees typically do the job. This is one wildflower that can be successfully cut and placed in a vase with water.
