Boldo (Peumus boldus)
Boldo is an evergreen tree that grows very slowly. It only grows about 6 to 8 meters tall. It produces a small fruit that resembles a berry. The flowers develop as either male or female, and each plant will only produce one sex or the other. The tree grows in the Andean area of Peru and Chile, as well as some parts of Morocco. Italy, Brazil and North Africa cultivate the trees to meet the commercial demands for this popular herb.
