An amaryllis of tropical America (Hippeastrum puniceum) often cultivated as a houseplant for its showy white to red flowers.

Hippeastrum is a genus of about 70-75 species and 600+ hybrids and cultivars of bulbous plants in the family Amaryllidaceae, native to tropical and subtropical regions of the Americas from Argentina north to Mexico and the Caribbean. Some species are grown for their large showy flowers. These plants are popularly but erroneously known as Amaryllis, an African genus in the same family.
