NOTOC{{Speciesbox

Yareta or llareta (in Spanish), known scientifically as Azorella compacta, (historically Azorella yareta) is a velvety, chartreuse cushion plant in the family Apiaceae which is native to South America. It grows in the Puna grasslands of the Andes in Peru, Bolivia, northern Chile and western Argentina at altitudes between 3200 and.

Distribution of flowers

The name comes from yarita in the Quechua language.

Description

Yareta is an evergreen perennial with a low, mat-like shape and hemispherical growth form that grows to around 6 m in diameter. The self-fertile, pink or lavender flowers are hermaphroditic and are primarily pollinated by small flies, bees, wasps, and moths.

The plant prefers sandy, well-drained soils. It can grow in nutritionally poor soils that are acidic, neutral or basic (alkaline) at altitudes of up to 5200 m. This mat grows near the ground where air temperature is one or two degrees Celsius higher than the mean air temperature. This temperature difference is a result of the longwave radiation re-radiated by the soil surface, which is usually dark gray to black in the Puna.

Yareta is estimated to grow approximately 1.5 cm per year. These oldest ones have been reported to grow as slowly as 1/18 in per year. Its very slow growth makes the traditional practice of harvesting it for fuel highly unsustainable.
