The leaves are often called yerba (Spanish) or erva (Portuguese), both of which mean “herb”. They contain caffeine (known in some parts of the world as mateine) and also contains related xanthine alkaloids and are harvested commercially. Prefers dappled sun and moderate water. Available in 1 gallon pots.
