The Sudanic region in the south of Mali receives approximately 28 to 39 inches of rain every year. This zone is an area of herbaceous vegetation, which means that the plants here are mostly herbs that have leaves and stems that die down at the end of growing season. This area of Mali is characterized primarily by its vast grass landscape, which is dominated by flowering trees. Species include the baobab, cailcedrat, sheanut, bastard mahogany and kapok.
The Sahel is an eco-climactic zone of transition between the Sahara desert in the north of Mali and the Sudanese savannas in the south. The Sahelian zone receives approximately eight to sixteen inches of rainfall every year, and in Mali it is characterized by steppes. Plant cover in steppe territories is usually thorny and thick leaved. Th Sahel territory is dominated by species of the flowering acacia tree. The acacia tree can survive in Mali's steps because it is able to thrive with little water and very poor soil quality. This is important because the steppes are sandy and rocky.
The Sahara region of Mali is part of the world's hottest desert, the Sahara, and receives little to no rainfall every year. Flowers found in this region of Mali are usually thick leaved, thorny plants like cactus. These plants must survive with very little water and flowering plants are rare. Some species of cactus in the sahara, including mimosas, will flower. The sahara also has acacia gum trees that flower. Near the oases, which are few and far between, you might find a flowering date palm.
