A self-watering Desert Plant !!

The desert Rhubarb (Rheum palaestinum) found in the Negev desert in Israel has leaves which can reach one meter in diameter, whereas other desert plants have small and spiky leaves. Israel scientists have discovered that it had unique self-watering mechanism that allows this to happen. They claim that this is the first example of self-irrigation in the plant ever found. The waxy leaves of the plant have deep and wide channels resembling a mountainous range that allows the droplets of water to be captured and then guided so that they fall on the soil near the roots of the plant.

Even in light rain, the water that fell near the roots was ten times more than that fell in other areas near the plant, due to this built in harvesting mechanism.
