Arabica Coffee A Rubiaceae ARABIAN Coffee Plant Guide

It is not generally known that the coffee tree makes an excellent houseplant. It is evergreen and may grow to a height of 6ft/1.8m, although there is a compact form, Cojfea arabica ‘Nana,’ that remains considerably smaller.

From its third or fourth year it may even bear flowers and fruit. The uncooked beans can, however, be poisonous, and they must be properly roasted before they can be made into coffee; this important process is best carried out by a professional.

The plant has shiny, dark green elliptical leaves with wavy edges; they can be as much as 6in/15cm in length and about 2in/5cm wide. 

The fragrant, star-shaped white flowers are followed by green fruits lA\n! 13mm long, which change to bright red and then to almost black as they ripen. The two seeds within the fruits contain caffeine.
