Cantua buxifolia, (/ˈkæntjuə bʌksɪˈfoʊliə/, Hispanicized spellings cantuta, cantu), known as qantu, qantus or qantuta (Quechua,[1]) is a flowering plant found in the high valleys of the Yungas of the Andes mountains in western South America.

Both kings were powerful and wealthy rulers of a vast country in the Qullasuyu region (today's Bolivian Altiplano), and each had a beloved son whom the people held in great esteem.

Then appeared Pachamama, goddess of fertility, who told the young kings before they died that they should not have suffered from their fathers' unjustified enmity.

To punish their dead fathers, their stars fell from the sky and became the snow-covered mountains still named Illimani and Illampu which are some of the highest peaks in Bolivia.

The cantua bloom symbolizes the people's unity, and bears the colours of the two kings' sons (red and yellow), as well as green (standing for hope).
