Salsify produces multiple stems one to three feet tall that when torn emit a milky sap. The leaves are long and very narrow. Each branch produces one flower head. The daisy-like yellow flowers open early in the morning and often close by late afternoon. The longer the days the more likely it is to flower.

Dalmation toadflax grows up to four feet tall on a stout, erect, branching stem.

The flowers are about an inch long, with two lips and a pronounced opposing spur. The bottom lip is raised and covered with orange hairs.
