The Goatsbeards or Salsifies are the genus Tragopogon of flowering plants within the family Asteraceae.

Goatsbeards are forbs growing as biennial or perennial plants. They have a strong taproot and milky sap. They generally have few branches, and those there are tend to be upright. Their leaves are somewhat grass-like. Flower colour varies within the genus, with some yellow species, and some bronze or purple. Seeds are borne in a globe like that of a dandelion but larger, and are dispersed by the wind. A forb is a non-woody flowering plant that is not a grass. ...

The goatsbeards are natives of Europe and Asia, but several species have been introduced into North America and Australia and have spread widely there. Europe is conventionally considered one of the seven continents of Earth which, in this case, is more a cultural and political distinction than a physiographic one, leading to some dispute as to Europes actual borders. ...

Some of the commoner species of Tragopogon are known, in the regions where they are commonest, by the common names "goat's beard", "goatsbeard", "salsify" or "common salsify", without further qualification. These names are therefore inherently ambiguous, and best avoided, or reserved for the genus collectively. In the species list below, the first common name given is the one that seems to be most widely used for that species and is not in significant use for any other species.

The vegetable called salsify is usually the root of Purple Salsify, Tragopogon porrifolius; the root is described as having the taste of oysters (hence the alternative common name "Oyster Plant" for some species in this genus). The young shoots of Purple Salsify can also be eaten. Other species are also used in the same way, including the Black or Spanish Salsify, Scorzonera hispanica, which is closely related though not a member of the genus Tragopogon.

The rise of new species

Goatsbeard are one example of when speciation has been observed. In the early 1900s, humans introduced three species of goatsbeard into North America. These species, T. dubius, T. pratensis, and T. porrifolius, are now common weeds in urban wastelands. In the 1950's, botanists found two new species in the regions of Idaho and Washington, where the three species overlapped. One new species, T. miscellus, is a tetraploid hybrid of T. dubius and T. pratensis. The other species, T. mirus, is also an allopolyploid, but its ancestors were T. dubius and T. porrifolius. The T. mirus population grows mainly by reproduction of its own members, but additional episodes of hybridization continue to add to the T. mirus population. Speciation refers to the evolutionary process by which new biological species arise. ... In biology, a species is the basic unit of biodiversity. ...
