Arid Regions Conservatory
Desert-dwelling plants are striking examples of nature's ability to adapt.
Some come from the arid regions of Africa (euphorbias, aloes), others from America (cacti, agaves), but they have much in common.
Their leaves are reduced to spines or covered with a waxy film to limit evaporation, while their stems expand to store water.
They will fight for the smallest drop of water, which explains why they grow so far apart in their natural environment.
That distance has been artificially reduced under the glass dome of this greenhouse.
