Haifa, Israel -- Israeli scientists say they have discovered the self-watering mechanism of the Negev desert rhubarb, which harvests 16 times more water than other plants.
Researchers at the University of Haifa-Oranim said the desert rhubarb grows in the mountains of Israel's Negev desert, where average precipitation is particularly low. Unlike most other desert plants that have small leaves to minimize moisture loss, the desert rhubarb is unique in that its leaves are particularly large; each plant's rosette of one to four leaves reaches a total diameter of up to slightly more than three feet.
