Habitat/ecology:  In Hawai‘i, "naturalized in dry, open areas such as along roadsides and in pastures, 60-3,050 m"  (Wagner et al., 1999; pp. 522-523).  In New Zealand, "roadsides, waste land, railway ballast, dry pasture, arable land, gardens, riverbeds, sand dunes, rocky bluffs, lake shores"  (Webb et al., 1988; 500).  In the United States, "Dry, open places, sandy and gravelly ground, roadsides, waste land; 0-2000 m"  (Flora of North America online).  "In Chile this species grows in the following environmental conditions:  Low altitude, interior valleys; coastal mountains, 500-2000 m; coastal areas, 0-500 m.  Somewhat dry areas where the drought may last 3-5 months; precipitations of 400-800 mm. are concentrated in winter; dry, arid areas, with long drought periods of 6-10 months. Precipitations of 100 mm-300 mm. are concentrated in winter.  Fully exposed to the sun; level areas or slopes facing north; some shadow; some protection against direct sunlight, some shadow from vegetation, filtering about 20-40% of light"  (Chileflora).
