Driest Place on Earth Erupts in Bloom


After intense and unexpected rain fell in the north of Chile, parts of the usually arid Atacama desert have turned into a carpet of flowers. (BBC)

What other deserts experience periodic “superblooms”?

Discussion Ideas



  • What plant life normally survives the arid Atacama?
    • Well, the dormant seeds that flower during a desierto florido event are still alive during the Atacama’s arid periods. They’re just not blooming!
    • Besides the dormant flower seeds, hundreds of plants have adapted to life in the high desert. These include dozens of endemic species of drought-tolerant plants such as cacti, saltgrass, and succulents.
    • Perhaps the most famous of the Atacama’s plant community is the yareta—what appears as a blob of bright green slime is actually the world’s highest-elevation woody plant. To conserve resources such as heat, moisture, and energy, the yareta is very dense and grows very slowly—a little more than one centimeter a year.
The yareta belongs to the same plant family as carrots and celery.
