Unusual Rainfall Brings Winter Flowers to Atacama Desert

COPIAPO, Chile (AFP-Jiji) — Large swaths of the Atacama desert, the driest on the planet, have been covered with purple and white flowers after unusual rainfall patterns in northern Chile.

Normally, such a desert bloom occurs every few years in the southern springtime — if and when conditions are just right — blanketing thousands of square kilometers.

But the flowers are making an appearance now in winter, something that hasn’t happened since 2015, experts say.

Cesar Pizarro, head of biodiversity conservation at the National Forestry Corporation, told AFP that 11-12 millimeters of rainfall in April “plus low cloud cover that has been very intense in the area and that wets these surfaces every night, helped activate these plants.”

While the famed spring flowering desert spreads over 15,000 square kilometers, this winter efflorescence is covering only a few hundred square kilometers.

When the bloom is at its peak, more than 200 plant species blossom. Recent weather conditions appear to have mainly suited the “pata de guanaco,” a purple flower that barely requires water and prefers sandy sites.
