What type of natural vegetation is present at Sahara desert?

The Sahara Desert is often described as a bleak and barren plain. In truth, it is very beautiful and full of different Sahara Desert vegetation.

There are still some areas of the Sahara Desert that can be considered lush and green. The Nile Valley, for example, is an area that is still quite full of foliage, trees and other growing things. This area is an exception, because of the way it is fed by the Nile River. Another area of the Sahara that has some vegetation to it is in the North, along the Mediterranean - here, olive trees grow in abundance. The Saharan highlands are also home to species of trees, such as the doum palm, date palm and oleander; as well as herbs such as thyme.

The rest of the Sahara Desert is sparse and vegetation does not cover much of the area. Here, away from rivers and highlands, grasses and shrubs that have adapted to the high heat of the area manage to survive. Also, halphytes, which are saline-tolerant plants (those plants which can grow in areas of high salt content) grow in the saline depressions of the Sahara. For a desert area, the Sahara manages to have many different types of vegetation, all of which have had to adapt to the unique challenges of a dry desert climate.
