"Petite herbacée à rosette, reconnaissable à sa rosette de feuilles ovales et son inflorescence dressée" (Meyer, 2008; p. 25).

Habitat/ecology:  "Occasional to common in lawns and other disturbed, sunny places" (Whistler, 1988; p. 33).

In Hawai‘i, "naturalized and sometimes locally common in beach parks, coastal sites, open pastures and sometimes in open sites in mesic forest and subalpine shrubland, 0-3,110 m" (Wagner et al., 1999; p. 1051).  In Niue, "very common weed in plantations and waste places" (Sykes, 1970; p. 169).  In Tonga, "occasional as a dooryard and waste-area weed" (Yuncker, 1959; p. 244). In New Zealand, "generally open modified places, particularly poor pastures, also a pioneer of river beds, landslips, coastal sands and talus, and cliff faces, common on many small offshore islands and often in remote coastal areas where very few other naturalised spp. occur" (Webb et al., 1988; p. 948).

Propagation:  Seed

Native range:  Europe and north-central Asia, widely naturalized (Wagner et al., 1999; p. 1051).

Control: 

Physical:  "Grazing or mowing may reduce the plant's growth"  (Weber, 2003; p. 335).

"La lutte manuelle par arrachage des plants est délicate sur les sites archéologiques (murets de pierre)"  (Meyer, 2008; p. 25).

Chemical:  "Effective herbicides are 2,4-D, MCPA dicamba, or fenoprop"  (Weber, 2003; p. 335).

"La lutte chimique ponctuelle par pulvérisation d’un herbicide sur les feuilles des plants en phase rosette (glyphosate ou paraquat) est possible" (Meyer, 2008; p. 25).
