There are many African landraces, some of which profoundly influenced modern cannabis genetics. Strains like Durban Poison, Kilimanjaro, Malawi Gold, and Congo were and are still widely used by breeders to create new hybrids, but many more are to be discovered. Almost all African landraces are pure Sativa plants that reach impressive heights and follow a long flowering cycle that lasts 12 to 14 weeks. They require hot environmental conditions and high humidity for optimal results, resulting in above-average yields. The aroma and flavor usually consist of woody and spicy herbal notes on a background of citrus and some tropical fruitiness, but there are many variations. The effects are mainly cerebral and energizing, causing euphoric feelings, the urge to get things done, and sometimes psychedelic-like thoughts that can be overwhelming to novice consumers. They often put you in a talkative mood. Medically, these strains are best suited for people dealing with depression, stress-related issues, chronic fatigue, and a lack of appetite.
