Botanical Name: Coffea arabica
Coffee plant is the source of the world's most popular breakfast beverage. Not many know, however, that it makes a beautiful and easy-to-grow house plant.
This member of the Rubiaceae family is one of 90 in the Coffea genus. It is an evergreen shrub that has glossy, dark-green leaves with ruffled edges on willowy stems.
Coffee bean plant can reach 15 ft 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.
Pruning tip: Prune coffee plant back in spring to keep it bushy and full. It also gives it an attractive shape. Use clean pruning shears to cut the stem at a 45° angle, 1/4-inch above a leaf axil (the place where a leaf attaches to the stem).
Repot in spring, moving to a pot 1 size larger. Use a pot with a drainage hole to avoid soggy soil.
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. Inside each ripened fruit are 2 seeds (or beans) that when properly roasted can be ground and made into coffee.
Growing coffee plants indoors is easy. They are vigorous growers and are long-lived. They make attractive house plants, just don't expect them to offer that morning cup of joe. It could take a few years before you see many fruits on it.
