Although the cultivation of coffee as a crop in temperate climates is not possible in an economically and ecologically sound way, a cultivation experiment in your house or greenhouse can still be very exciting. Coffee is a deep-rooting plant, so you should definitely use high flower pots.
The majority of people are familiar with coffee seeds only in their roasted form: irresistibly fragrant coffee beans. Still green, unprocessed coffee beans are nothing else but coffee seeds, sometimes called coffee cherries or green coffee. To cultivate a plant from raw coffee seeds, they should not be very old, because they are capable of germination only for a short period.
