The Plant Life of Kilimanjaro
Plant life is featured in my book Kilimanjaro: One Man’s Quest to Go Over the Hill, which chronicles my attempt to summit Mount Kilimanjaro, the highest mountain in Africa. The book is on sale now as an e-book for $3.99 and in paperback for $9.99 from Amazon and other booksellers.
Diverse vegetation from different climate zones graces the slopes of Kilimanjaro. One of the more unique places on Earth, the mountain lies in Africa’s Afromontane region that straddles the Equator with clusters of freestanding mountains and plateaus surrounded by lowlands. A sky island more at home in the far reaches of the northern and southern hemispheres than the equatorial tropics, Kilimanjaro has amazing biodiversity.
Within days, mountaineers can hike through five different climate zones. These are:
- Lowlands: Between 2,600 and 5,900 feet (790-1,800 meters), this is the subtropical area located just above the Serengeti plains. An area with heavier rainfall, its vegetation is dominated by banana, coffee, and other plants grown as crops.
- Rainforest: Between 5,900 and 9,200 feet (1,800-2,800 meters), this is a subtropical rainforest rich with plant and animal life. The widest variety of flowering plants range in this zone.
- Moorland and heather: Between 9,200 feet and 13,100 feet (2,800-4,000 meters), this area has less vegetation and is dominated by a few plant and animal species, including groundsels, lobelias, heather, and tree moss. Trees disappear above 13,000 feet.
- Alpine or high desert: Between 13,100 and 16,400 feet (4,000-5,000 meters), this arid, semi-desert zone has no trees and few plants. Sage grass, hearty helichrysum flowers, moss, and thistles are common there.
- Arctic or summit: Above 16,400 feet (5,000 meters), this is an arid zone with intense sunlight, thin air, and heavy snow and ice. Few to no plants grow there.
The southern and western slopes of Mount Kilimanjaro are wetter than its northern and eastern sides. The city of Arusha to the west of Kilimanjaro sits in a tropical bowl, while the Serengeti Plains to the northeast are dry.
Here are some of the species of plant I encountered during my climb.
Mackinder’s Gladiolus (gladiolus watsonioides)
African blood or fireball lily (scadoxus multiflorus)
Hibiscus rosa-sinensis

Helichrysum meyeri johannis
The south side of Kilimanjaro is a fertile landscape filled with windswept views of stunted forests and swaths of vegetation. In the subtropical lowlands, wispy bunches of tree moss hang from the trees like tattered voiles ready to spring back to life when the rains return, transforming the forest into a fantasy land.

The north side of Kilimanjaro offers a more Alpine landscape with heather and moorlands dominated by tussock or bunch grass. The view there is more desolate and, in some ways, more intriguing as the vegetation quickly gives way to the exposed mountain. Mountaineers who climb fields of rust-tinged rocks are often left with the impression that they are on the surface of Mars.

In the highlands, the view is dominated by groundsel trees, or dendrosenecios, with trunks like palms and topped with spiky leaf rosettes, as well a cactus-like flowering plant known as the lobelia deckenii.

Because few plants grow in the high desert, those that do such as sage grass and lobelia deckenii are photo ready. Unlike humans, the vegetation is hearty enough to survive the harsh climate on Kilimanjaro. Still, the mountain has a way of twisting everything at this altitude into bizarre and fascinating shapes.

If you’re thinking about climbing Mount Kilimanjaro, imagine yourself hiking through these places over a few days. If you’ve already been there, I hope that these photos will bring back memories and help you put names to some of the beautiful foliage you saw on your way to and from the summit.
