Everything about Tragopogon totally explained

The
Goatsbeards or
Salsifies are the
genus Tragopogon of
flowering plants within the family
Asteraceae. They include the
vegetable called salsify as well as a number of common wild flowers, some of which are usually regarded as
weeds.
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.
The goatsbeards are natives of
Europe and
Asia, but several species have been introduced into
North America and
Australia and have spread widely there.
Some of the more common species of
Tragopogon are known, in the regions where they're most common, 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 isn't 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), but more insipid with a touch of sweetness. 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 where
hybrid speciation has been observed. In the early 1900s, humans introduced three species of goatsbeard into North America. These
species, the
Western Salsify (
T. dubius), the
Meadow Salsify (
T. pratensis), and the
Oyster Plant (
T. porrifolius), are now common weeds in urban wastelands. In the 1950s, botanists found two new species in the regions of
Idaho and
Washington, where the three already known species overlapped. One new species,
Tragopogon miscellus, is a
tetraploid hybrid of
T. dubius and
T. pratensis. The other species,
Tragopogon mirus, is also an
allopolyploid, but its ancestors were
T. dubius and
T. porrifolius. These new species are usually referred to as "the Ownbey hybrids" after the botanist who first described them. 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.
