Tamarillo best known by the name tree-tomatoes in Kenya is a fast-growing tree that grows up to 5 meters. Peak production is reached after 1-3 years, and the life expectancy is about 12 years. The tree usually forms a single upright trunk with lateral branches. They produce 1 to 6 fruits per cluster. Plants can set fruit without cross-pollination, but the flowers are fragrant and attract insects. Cross-pollination seems to improve the fruit set.
