The Yellow Salsify (Tragopogon dubius), aka western goat’s-beard and wild oysterplant, is a pretty and quite common flower that can easily be mistaken for a jumbo dandelion. It is an introduced species in the U.S. and has spread to nearly all of the lower 48 states.
The roots of this plant are edible, although this is NOT the same salsify species whose roots are starting to show up regularly in farmer’s markets and health food store produce sections in the U.S.
Salsify, with its abundance of pollen, is a favorite among bees.
When finished flowering, the Yellow Salsify forms a seed head similar to that of the dandelion, but is much larger.
