Climate of the native range

The Köppen climate classes found in the areas this plant is recorded as native to. It does not mean an entire area has that climate.

  • Cfb Temperate, no dry season, warm summer
  • BWh Arid, desert, hot
  • BSk Arid, steppe, cold
  • BSh Arid, steppe, hot
  • Cfa Temperate, no dry season, hot summer
  • ET Polar, tundra

The same climate occurs in 129 areas worldwide, 116 of which have no record of this plant. See them on the map

A matching climate does not mean the plant can grow there. Range limits are also set by things other than climate — dispersal history, soils, competition. Source: Beck et al. (2023), CC BY 4.0 (observed period 1991–2020).
