Achiote (Bixa orellana) is a shrub or small tree from the tropical region of the American continent. The name derives from the Nahuatl word for the shrub, achiotl. It is also known as Aploppas, and its original Tupi name urucu. It is cultivated there and in Southeast Asia, where it was introduced by the Spanish in the 17th century. It is best known as the source of the natural pigment annatto, produced from the fruit. The plant bears pink flowers and bright red spiny fruits which contain red seeds. The fruits dry and harden to brown capsules.
