Seeing waves of purple along the side of the road? You’re looking at Canada toadflax, a Florida native that blooms when the weather has become consistently warm and sunny, generally starting in late February.
Canada toadflax is a small plant, extending four to eight inches above the ground. The flowers are pale blue to violet. They’re small, about a third of an inch long, but the plant often grows in clusters, and sheer numbers help make up for the lack of size. With its different hues of purple and blue, Canada toadflax can put on an impressive display.
