Coffee – (Coffea arabica)
Coffee comes from the Coffea arabica tree that grows in warm regions of the world like Latin America, Africa and Southeast Asia. The evergreen trees grow on the cooler mountain slopes. The seeds, or beans, are picked when they ripen. The seeds are then sorted and processed before being sent to be roasted. The beverage made from them is popular all over the world and I could write a whole website on this herb alone!
