Chuquiraga is a genus of flowering plants in the aster family, Asteraceae, containing about 20[1] to 23 species.[2] The genus is distributed in the Andes from Colombia to Chile, with most species occurring in Patagonia.[1]

These are evergreen shrubs. They have many shapes and sizes of leaves, and two general types of flowers apparently adapted for pollination by hummingbirds and insects.[3] Some species occur at elevations over 4000 meters in the Andes, while others can be found at sea level.[4]

Many are of ecological importance because they are dominant plant species in very dry habitat types, and local animals depend on them.[5] Hummingbirds of the genus Oreotrochilus, the hillstars, rely heavily on these plants, and some species have never been observed on any other plant taxa.[6]

Some species have been used as fuel, as traditional medicines, and as ornamental plants.[5]

Species include:[7]

  • Chuquiraga acanthophylla
  • Chuquiraga arcuata
  • Chuquiraga atacamensis
  • Chuquiraga aurea
