Permanent dripping spring provides water for a congenial habitat for many desert plants.Ein Avdat's soil and water are slightly saline and the canyon's plants have accommodated to salty conditions. The Saltbush has adapted especially well; hairs on its leaves absorb the salt and then fall off, allowing the plant to survive. Salt colors this green plant with a silver sheen.

Next to the canyon wall there is an Atlantic Pistachio tree. It is very rare to find trees of this kind at such low altitude - only 350 meters above sea level - for they only usually grow at double this height. Atlantic Pistachio can survive on as little as 200 millimeters of rain per year and still produce fruit. At the top of the waterfall is a grove of Euphrates Poplar trees. Found across Asia and all the way to Northwest Africa, this type of tree has taken root in only four Negev locations - yet another indication of a once water and colder climate in Ein- Avdat. Eupharates Poplar are especially beautiful in autumn, when they turn yellow before shedding their leaves. The hetrogenious vegetation in the oasis comprises many more species adopted to various habitats surrounding the water. Among them are Reed, and Ferns on the water fringe, Tamarax, Palms and Secculents nearby and Caprys on the rocky walls.
