''Sonchus'' is a genus of flowering plants in the tribe Cichorieae within the family Asteraceae and are commonly known as sow thistles (less commonly hare thistles or hare lettuces). Sowthistles are annual, biennial or perennial herbs, with or without rhizomes and a few are even woody (subgenus ''Dendrosonchus,'' restricted to the Canary Islands and Madeira). Description The genus is named after the Ancient Greece, Ancient Greek for such plants, σόγχος. All are characterized by soft, somewhat irregularly lobed leaves that clasp the stem and, at least initially, form a basal rosette. The Plant stem, stem contains a milky latex. Head (botany), Flower heads are yellow and range in size from half to one inch in diameter; the flower, florets are all of ray type. ''Sonchus'' fruits are single-seeded, dry and Dehiscence_(botany), indehiscent. Sow thistles are common roadside plants, and while native to Eurasia and tropical Africa, they are found almost worldwide in temperate regi ...

Temperate
In geography, the temperate climates of Earth occur in the middle latitudes (approximately 23.5° to 66.5° N/S of the Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small; they usually differ only in the amount of precipitation. In temperate climates, not only do latitude, latitudinal positions influence temperature changes, but various sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistence of frost. However, some adaptations of Köppen set the minimum at . Continental climate, Continental climates are classified as D and considered to be varie ...

Sonchus Asper
''Sonchus asper'', the prickly sow-thistle, rough milk thistle, spiny sowthistle, sharp-fringed sow thistle, or spiny-leaved sow thistle, is a widespread flowering plant in the tribe Cichorieae within the family Asteraceae. Description ''Sonchus asper'' is an annual or biennial herb sometimes reaching a height of with spiny leaves and yellow flowers resembling those of the dandelion. The leaves are bluish-green, simple, lanceolate, with wavy and sometimes lobed margins, covered in spines on both the margins and beneath. The base of the leaf surrounds the stem. The leaves and stems emit a milky sap when cut. One plant will produce several flat-topped arrays of flower heads, each head containing numerous yellow ray flowers but no disc flowers. Distribution ''Sonchus asper'' is native to Europe, North Africa, and western Asia. It has also become naturalized on other continents and is regarded as a noxious, invasive weed in many places. Its edible leaves make a palatable and nutr ...

Sonchus Arvensis
''Sonchus arvensis'', the field milk thistle, field sowthistle, perennial sow-thistle, corn sow thistle, dindle, gutweed, swine thistle, or tree sow thistle, is a species of flowering plant in the family Asteraceae. ''S. arvensis'' often occurs in annual crop fields and may cause substantial yield losses. Description The plant grows up to in height, with leaves long and wide. It produces conspicuous yellow flowerheads about wide, which are visited by various types of insects—especially hoverflies of the genus '' Eristalis''. Distribution ''Sonchus arvensis'' is native to Eurasia, where it is widespread across most of the continent. It has also become naturalized in many other regions, and is considered an invasive noxious weed in some places, such as North America (including Prince Edward Island), Russia, New Zealand, and Australia. It grows in areas such as pastures, roadsides, bushlands and the shorelines of lakes, rivers and sea coast. A study conducted in 2003 has s ...
