Plant Description and Details
Roadsides host scattered specimens, but a concentrated patch of Mt. Thermopsis can be quite a winning sight. We raised a field for seed and saw first hand how the soft-textured, rounded leaves sprang up from their hearty 2-year-old roots thenburst into exuberant yellow pea blossoms. The pollinators were just as pleased as we were. Lumbering bumblebees, especially, spent hours opening the hinged pea flowers to reach the pollen.
