The Coffee Tree is a shrubby evergreen plant that produces fragrant white flowers in early spring, followed by small oblong fruits called “cherries.” The cherries can take up to nine months to ripen to a red-purple color and often contain two coffee beans inside them. The beans are harvested to either produce coffee plants or roast for coffee beverages. Hardy to zones 10B through 11, coffee trees have a shallow root system, rounded growth habit and can reach as much as 30 feet tall at maturity. The coffee tree can be grown indoors under plant lights or bright indirect sunlight or outdoors in sub-tropical regions. The coffee tree is an evergreen. It does not shed its leaves. It is a beautiful houseplant that produces a significant amount of oxygen. You can get it to grow into a tree or train it to be a bush 3-4 feet tall.
The Coffee tree, Coffea Arabica, is known for the flavor or its coffee beans. It is self-pollinating.
The Coffee Tree Coffea Robusta is not self-pollinating. The robusta plant has a greater crop yield than that of arabica, contains almost twice the caffeine and is less susceptible to pests and disease than Arabica.
