Both Alstroemeria and Sprekelia are called lillies, but are they from the same family?
Alstroemeria Alstroemeria ( ), commonly called the Peruvian lily or lily of the Incas, is a genus of flowering plants in the family Alstroemeriaceae. They are all native to South America although some have become naturalized in the United States, Mexico, Australia, New Zealand, Madeira and the Canary Islands. 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. graminea", a diminutive annual from the Atacama Desert of Chile.
Nuttallanthus Nuttallanthus is a genus of four species of herbaceous annuals and perennials that was traditionally placed in the foxglove family Scrophulariaceae. Due to new genetic research, it has now been placed in the vastly expanded family Plantaginaceae. Three species of "Nuttallanthus" are native to North America and one to South America. "Nuttallanthus" was until the 1980s included in a wider circumscription of the genus "Linaria", a genus now considered restricted to the Old World.
