Definition of Alstroemeria

Alstroemeria (syn. Alstremeria), commonly called the Peruvian Lily or Lily of the Incas, is a South American genus of about 50 species of flowering plants. Almost all of the species are restricted to one of two distinct centers of diversity, one in central Chile, the other in eastern Brazil. Species of Alstroemeria from Chile are winter-growing plants while those of Brazil are summer-growing. All are long-lived perennials except A. (Taltalia) graminea, a diminutive annual from the Atacama Desert of Chile.
