About
Cantua buxifolia, (, Hispanicized spellings cantuta, cantu), known as qantu, qantus or qantuta (Quechua) is a flowering plant found in the high valleys of the Yungas of the Andes mountains in western South America. Also known as the Peruvian magic tree, it is an evergreen shrub growing to 4 m (13 ft) tall by 2.5 m (8.2 ft) wide with small leaves and clusters of brilliant pink, narrow tubular flowers in early spring.
It is the national flower of Peru and one of two national flowers of Bolivia, the other being the patujú (Heliconia rostrata).The Bolivian national flower is in fact a particular variety of qantuta, the qantuta tricolor, which has red petals, a yellow floral tube and a green calyx, reflecting the colors of the national flag.
