Hippeastrum, say it out loud, Hippeastrum. What an ugly name for an Amaryllis, right? Hippeastrum is a genus in the Amaryllidaceae family. Depending on the source Hippeastrum means either "horseman's star," "knight's star" or "horse's Star". Why? Nobody really knows. What the experts, fancy gardeners and botanists know is that Amaryllis isn't the proper name for these bulbs, and yet we persist on using the name. Maybe it is because the word sounds as beautiful as the blooms look. 'Lemon Lime' is my latest Amaryllis to bloom and it looks remarkably like my 'Mont Blanc,' but greener. 'Lemon Lime' is one of the "green" hybrid Amaryllis bulbs, the coloration and shape of the bloom can vary from bulb to bulb.
