Family: Plantaginaceae · Type: annual · Native

Snapdragon is a California native annual found in southern North Coast Ranges, Sutter Buttes, San Francisco Bay Area, and northern South Coast Ranges in gravelly lower slopes, rockslides, and disturbed areas, often on serpentine at elevations below 1,200 meters.

Growing with erect stems 7 to 170 centimeters tall, the plant has sparse proximal stem hairs less than 3 millimeters long. Its inflorescence branches feature two leaves at the proximal-most node, with an unusual calyx structure where the upper lobe measures 6.8 to 14 millimeters and the lower lobe 4 to 8.6 millimeters long. The flower corolla ranges 11 to 17 millimeters in length, creating a delicate and intricate appearance.
