Tragopogon, also known as goatsbeard [4] or salsify, is a genus of flowering plants in the family Asteraceae. It includes the vegetable known as salsify, as well as a number of common wild flowers.
Salsifies 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 achenes and are borne in a globe like that of a dandelion but larger, and are dispersed by the wind.
The salsifies are mostly natives of Europe and Asia, but several species have been introduced into North America and Australia and have spread widely there. There is one species sometimes considered native to North America, Tragopogon mirus , but it is in fact a hybrid of two non-native species. [5]
Some of the more common species of Tragopogon are known, in the regions where they are 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 is not in significant use for any other species.
The vegetable called salsify is usually the root of the 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, as well as young leaves . 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 name Tragopogon comes from Ancient Greek τράγος (trágos) 'billy goat',and πώγων (pṓgōn) 'beard'. [6]
Salsifies are one example where hybrid speciation has been observed. [7] [8] 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 in urban areas. 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 hybrid speciation continue to add to the T. mirus population. [9]

The following species were once included in Tragopogon and are now regarded as better suited to other genera: Agoseris, Geropogon, Krigia, Lasiospora, Nothocalais, Podospermum, Scorzonera, Taraxacum, and Urospermum.
Senecio is a genus of flowering plants in the daisy family (Asteraceae) that includes ragworts and groundsels.
Scorzonera hispanica, commonly known as black salsify or Spanish salsify, also known as black oyster plant, serpent root, viper's herb, viper's grass or simply scorzonera, is a perennial member of the genus Scorzonera in the sunflower family (Asteraceae), cultivated as a root vegetable in the same way as purple salsify, also in the sunflower family. It is native to Southern Europe and cultivated as a crop in Southern and Central Europe. It grows on nutrient poor soils, dry pasture, rocky areas, in thickets and on limy or marly soils of temperate zones.
Goatsbeard or Goat's beard is a common name for several plants and may refer to:
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. It is commonly known as purple or common salsify, oyster plant, vegetable oyster, Jerusalem star, Jack go to bed, or simply salsify.
Oyster plant is a common name used for various flowering plants, including:
Scorzonera is a genus of flowering plants in the tribe Cichorieae within the family Asteraceae.
Allium canadense, the Canada onion, Canadian garlic, wild garlic, meadow garlic and wild onion is a perennial plant native to eastern North America from Texas to Florida to New Brunswick to Montana. The species is also cultivated in other regions as an ornamental and as a garden culinary herb. The plant is also reportedly naturalized in Cuba.
Aruncus is a genus of clump-forming herbaceous perennial plants in the family Rosaceae. Botanical opinion of the number of species differs, with from one to four species accepted. They are closely related to the genera Filipendula and Spiraea, and are native to mountainous damp woodland in temperate regions of the Northern Hemisphere. Creamy white plumes of flowers are produced above veined and toothed leaflets.
Physocarpus, commonly called ninebark, is a genus of flowering plants in the family Rosaceae, native to North America and northeastern Asia.
Tragopogon pratensis is a biennial plant in the family Asteraceae, distributed across Europe and North America, commonly growing in fields and on roadsides. It is found in North America from southern Ontario to Massachusetts; most of England; on the eastern and southern edges of Scotland; and central Ireland but not the coastal edges.
Tragopogon dubius is a species of salsify native to southern and central Europe and western Asia and found as far north and west as northern France. Although it has been reported from Kashmir and India, recent evidence suggests that specimens from these areas may be a different species. Western salsify has been introduced into North America where it has become widespread, being reported from all the continental United States except for a few in the far south-east, and all provinces of Canada except Newfoundland and the northern territories.
Iva is a genus of wind-pollinated plants in the family Asteraceae, described as a genus by Linnaeus in 1753. Plants of this genus are known generally as marsh elders. The genus is native to North America.
Senecio eboracensis, the York groundsel or York radiate groundsel, is a flowering plant in the daisy family Asteraceae. It is a self-pollinating hybrid species of ragwort and one of only six new plant species to be discovered in either the United Kingdom or North America in the last 100 years. It was discovered in 1979 in York, England growing next to a car park and formally described in 2003. Like many of the Senecio genus it can be found growing in urban habitats, such as disturbed earth and pavement cracks and this particular species only in York and between a railway and a car park.
The Cichorieae are a tribe in the plant family Asteraceae that includes 93 genera, more than 1,600 sexually reproductive species and more than 7,000 apomictic species. They are found primarily in temperate regions of the Eastern Hemisphere. Cichorieae all have milky latex and flowerheads that only contain one type of floret. The genera Gundelia and Warionia only have disk florets, while all other genera only have ligulate florets. The genera that contain most species are Taraxacum with about 1,600 apomictic species, Hieracium with about 770 sexually reproducing and 5,200 apomictic species, and Pilosella with 110 sexually reproducing and 700 apomictic species. Well-known members include lettuce, chicory, dandelion, and salsify.
Hartwrightia is a genus of North American flowering plants in the tribe Eupatorieae of the family Asteraceae. The genus contains a single species, Hartwrightia floridana, native to the US states of Georgia and Florida. The species is sometimes referred to by the common name Florida hartwrightia.
Geropogon is a genus of flowering plants in the family Asteraceae.
Cassida panzeri is a species of beetle in the leaf beetle family, found in the Palearctic realm, and in the Honshu province of Japan. The host plants are in the family Asteraceae, and include Arctium lappa, Scorzonera humilis, Taraxacum officinale, Tragopogon pratensis and Cirsium species.
Tragopogon miscellus, the Moscow salsify, is a species native to the States of Washington and Idaho. Intensive studies over the course of many years have demonstrated that it originated as an allopolyploid hybrid between T. dubius and T. pratensis, both of which are European species naturalized in the US. Tragopogon miscellus has become established in the wild, reproducing by its own, thus deserving recognition as a species.
Tragopogon mirus, the remarkable goatsbeard, is a plant species considered native to certain regions of North America. Intensive studies over the course of many years have demonstrated that it originated as an allopolyploid hybrid between T. dubius and T. porrifolius, both of which are European species naturalized in the US. Tragopogon mirus has become established in the wild, reproducing by its own, thus deserving recognition as a species.
Tragopogon orientalis, common name Oriental goat's beard, is a hemicryptophyte herbaceous annual plant in the family Asteraceae.
