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.
Tall tumblemustard is a plant with many branches growing from a single stem and a stout taproot. It is initially a low-growing rosette of basal leaves, but later becomes tall and lanky in appearance, growing up to five feet in height. The round stems are light green and mostly smooth, except for widely scattered white hairs.
Western groundsel is a fairly tall plant (eight to twenty-eight inches) with a single upright stem and large, smooth-edged leaves. Although daisy-like, groundsels appear flat-topped with several to numerous small, yellow heads borne near the tips of equal-height branches.

Puccoon is common in the shrub-steppe, and is easily identified by a cluster of multiple long, leafy stems, eight inches to two feet tall, springing up from a woody tap root. The small, pale yellow-to greenish-white flowers of puccoon appear in late spring, partially hidden among the numerous leaves near the stem tip.
Dalmation toadflax grows up to four feet tall on a stout, erect, branching stem. It can easily be mistaken for a snapdragon with its bright yellow flowers that grow in a head at the end of the main 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.
