Tragopogon porrifolius is a plant cultivated for its ornamental flower and edible root. It also grows wild in many places and is one of the most widely known species of the salsify genus, Tragopogon. The plant grows to around 1.2 m (4 ft) in height. As with other Tragopogon species, its stem is largely unbranched and the leaves are somewhat grasslike. It exudes a milky juice from the stems. The taproots can become 15–30 cm (6–11+3⁄4 in) long and 2–5 cm (3⁄4–2 in) thick.
The root and the young shoots of T. porrifolius can be eaten (after being boiled)
