Hippeastrum Bulbs

Hippeastrum is widely and wrongly known as Amaryllis in the commercial world. Native to South America, the bulbous Hippeastrum species grow in a wide range of tropical, subtropical and just about temperate at high altitudes and south of the equator. Some grow in the underbrush, others like full sun, some prefer flood areas  while other species prefer a drier habitat and many epiphytic species exist as well which may be found living in natural debris and leaf litter on the crooks of tree branches.
Reproduction and propagation-wise, some species are sterile and unable to produce seeds, some reproduce asexually by producing many bulbils around the mother bulb, some colonising species are self pollinating reproducing by distributing seed and some reproduce through allogamy where seeds are only produced by pollination from other plants and pollinators include hummingbirds and moths.
