Looking like a well-driven wedge cleaving Algeria and Libya, Tunisia is dwarfed by its African neighbors, though it's not much smaller than most Mediterranean European nations. The mountains of the north-west occasionally get snow, while the farther south you go, the hotter and drier it gets.
Rainfall dictates what grows where in Tunisia.
The Kroumirie Mountains in the north-west receive the lion's share of the sprinkling and are densely forested with evergreen holm and cork oak. The strawberry tree is another common sight, named for its striking reddish fruit, which young boys can be seen hawking at the roadside in December. The trees are covered with dense panicles of fragrant white flowers in autumn. The small plains of the Tell contain small pockets of Aleppo pine, while Tunisia's last remnant of pre-Saharan savanna is found in the Acacia raddiana forest of Bou Hedma National Park. The treeless plains of the south support large areas of esparto grass, while farther south the vegetation gives way altogether to desert and the occasional oasis.
