Self-Irrigating Plant
Self-Irrigating Plant
The desert rhubarb grows in the mountainous deserts of Israel and Jordan, where there’s only about 75mm of rainfall each year. Plants with large leaves and a deep root system, like the desert rhubarb, typically can’t survive in such an arid climate. But somehow, this plant has apparently figured out how to water itself. Upon closer examination, scientists discovered deep grooves around the plant’s veins, which are coated in a waxy cuticle that helps channel water down to the root. Ridges in the plant’s giant leaves actually collect water and channel it down to the plant’s root system, harvesting up to 16 times more water than any other plant in the region. This is truly the first example of a self-irrigating plant.
