After the rains, which usually fall in the first two months of the year, grass grows up through the sand. Wadis have the richest plant life with bushes, shrubs and trees such as the yellow-flowered acacia.  After spring, wadis fill with the vibrant colours of purple iris, red bladder dock and other flowers. Birds and bees help to pollinate the plants.

Common names both in Arabic and other languages may differ from place to place.
