Wikipedia
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", although precisely what Herbert meant by the name is not certain. 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 this genus, often sold as indoor flowering bulbs particularly at Christmas in the northern hemisphere. By contrast the generic name Amaryllis applies to bulbs from South Africa, usually grown outdoors. The genus is native to tropical and subtropical regions of the Americas from Argentina north to Mexico and the Caribbean.
Reproduction is generally by allogamy (cross-pollination) and Hippeastrum may be propagated by seed or offset bulbils (bulblets), although commercial ventures use in vitro techniques, or splitting of the bulb into sections. The genus has been intensely bred and cultivated since the early nineteenth century to produce large colourful showy flowers. In temperate climes these can be placed outside in the summer, and after a dormancy period, be induced to rebloom inside in the winter.
Usage examples of "hippeastrum".
This case of the Crinum leads me to refer to a most singular fact, namely, that there are individual plants, as with certain species of Lobelia, and with all the species of the genus Hippeastrum, which can be far more easily fertilised by the pollen of another and distinct species, than by their own pollen.
This result has, also, been confirmed by other observers in the case of Hippeastrum with its sub-genera, and in the case of some other genera, as Lobelia, Passiflora and Verbascum.
