This coffee bean plant can reach 15ft or more in its native tropical habitat, but you can cut it back to control its size. Pruning harshly won’t hurt it at all. After 3 or 4 years, Coffea arabica produces star-shaped, sweetly scented white flowers. These flowers are followed by green fruits which change to red then to almost black as they ripen, a process that takes several months. Plant in partial shade where soils are rich in organic material, are moist but free-draining.
