Here is some detailed information on coffee trees.
Coffea is a large genus (containing more than 90 species) of flowering plants in the madder family, Rubiaceae. They are shrubs or small trees, native to subtropical Africa and southern Asia. Seeds of several species are the source of the popular beverage coffee. Coffee ranks as one of the world's most valuable and widely traded commodity crops and is an important export of a number of countries. The leaves and the outer part of the fruit are also sometimes eaten.
There are several species of Coffee that may be grown for the beans. The trees produce red or purple fruits called "cherries" that are drupes. The cherries contain two seeds, the so-called "coffee beans", which despite their name are not true beans (which are the seeds of the legume family). In about 5 to 10% of any crop of coffee cherries, there is only a single bean, rather than the two usually found.
This is called a "peaberry", which is smaller and rounder than a normal coffee bean. It is often removed from the yield and either sold separately, (as in New Guinea peaberry) or discarded.
When grown in the tropics, coffee is a vigorous bush or small tree which usually grow to a height of 3 to 3.5 m (10 to 12 feet). Most commonly cultivated coffee species grow best at high elevations, but are nevertheless intolerant of subfreezing temperatures.
The caffeine in coffee "beans" is a natural plant defense against herbivory, i.e. a toxic substance that protects the seeds of the plant.
Several insect pests affect coffee production, including the coffee borer beetle (Hypothenemus hampei) and the coffee leafminer Leucoptera caffeina.
