Arabian coffee

An evergreen shrub or tree to 8m, with opposite pairs of glossy, dark green leaves. Once plants are about 4 years old, small, white, fragrant flowers are produced in the leaf axils in summer; these are followed by green fruits that ripen over several months to red "cherries". Each fruit contains two seeds (coffee beans) and under ideal conditions it should be possible to harvest enough for a cup of home-grown coffee
