Coffea arabica (Arabian Coffee)

Coffea arabica is the species behind the majority of the world's commercial coffee, and it also makes a handsome, glossy-leaved houseplant with genuine ornamental appeal. The deep green, wavy leaves are attractive year-round, and mature plants produce clusters of small, fragrant white flowers that eventually develop into bright red coffee cherries. Expect 3-5 years before a plant flowers, and reliable fruiting indoors is difficult.

In our climate, Coffea arabica is strictly an indoor plant. It is tropical by nature, native to the forests of Ethiopia, and cannot tolerate temperatures below about 55 degrees F. Outdoors, it is only suitable in USDA zones 10-11. Indoors, it prefers bright indirect light, high humidity, and consistent warmth. Avoid cold drafts and direct harsh midday sun.

Water thoroughly when the top half-inch of soil dries out, and reduce watering slightly in winter. Feed monthly with a balanced liquid fertilizer during the growing season. The ASPCA classifies coffee plants as toxic to both dogs and cats. All plant parts contain caffeine, which can cause vomiting and agitation in pets.
