Prickly Sowthistle is occasional to locally common in Illinois. Apparently, it is uncommon or absent from many areas of NW, central, and southern Illinois, although official records probably underestimate its distribution (see Distribution Map). Habitats include irregularly mowed lawns, edges of yards and driveways, gardens, areas along roads and railroads, vacant lots, barnyards, and waste areas. This species prefers highly disturbed areas, and does not present an invasive threat to natural areas to any significant degree. It is native to Eurasia and North Africa. Faunal Associations

Sonchus asper (sharp-fringed sow thistle, prickly sow-thistle,[1] spiny sow thistle, or spiny-leaved sow thistle) is an annual plant 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 plant can reach 180 cm (6 ft) in height. The leaves and stems emit a milky sap when cut. The flowers grow in clusters and the end of the stems.
This plant is native to Europe, but is also a common weed in North American roadsides, landscapes, and pastures. Its edible leaves make a palatable and nutritious leaf vegetable.
The plant is classified as a noxious weed in some states, but not others.
This plant is a dicotyledon.

L. Boulos (1973) distinguished subsp. asper (annuals with leaves mostly cauline, cypselae margins little or not at all curved and/or ciliate, and one pair of chromosomes with small satellites) from subsp. glaucescens (biennials with leaves mostly in rosettes, leaves mostly stiffer and more prickly than in subsp. asper, cypselae with curved, ciliate margins, and two pairs of chromosomes with large satellites) and noted that the two subspecies are morphologically rather difficult to distinguish if the specimen in hand lacks the rootstock or stem base.
According to H. N. Barber (1941), crosses between Sonchus asper and S. oleraceus resulted in sterile hybrids.
