About Nuttall's Snapdragon (Antirrhinum nuttallianum) Antirrhinum nuttallianum is a species of New World snapdragon in the Plantaginaceae family known by the common names Nuttall's Snapdragon. It is native to southern California and Baja California, where it can be found from the immediate coastline to the inland coastal ranges.

The flowers are veined light purple with white patches and around a centimeter long. Each is borne on a short pedicel.
