Hippeastrum is a genus of about 90 species and over 600 hybrids and cultivars of perennial herbaceous bulbous plants. They generally have large fleshy bulbs and tall broad leaves, generally evergreen, and large red or purple flowers.

Hippeastrum is a genus in the family Amaryllidaceae [subfamily Amaryllidoideae, tribe Hippeastreae, and subtribe Hippeastrineae]. The name Hippeastrum, given to it by William Herbert, means “Knight’s-star-lily”.

For many years there was confusion among botanists over the generic names Amaryllis and Hippeastrum, one result of which is that the common name “amaryllis” is mainly used for cultivars of the genus Hippeastrum, widely sold in the winter months for their ability to bloom indoors.
