In general only a large bulb will put up more than one flower scape or spike but this depends on the cultivar itself; some smaller bulbs have two while some larger bulbs make only one. A bulb must produce at least four large, healthy leaves in the summer growing season before it can send up a scape the following year. Some bulbs put up two flower scapes at the same time; others may wait several weeks between blooms and sometimes the second scape will have only two or three flowers rather than the usual four. Dutch bulbs usually produce flowers first, then, after it has finished blooming, the plant will begin growing leaves. Bulbs from the South African growers usually put up a scape and leaves at the same time.
The flower colors include red, rose, pink, white, orange, yellow, and pale green with variations on these including different colored stripes and edges on the petals. Some flowers have uniform colors or patterns on all six petals while others have more pronounced colors on the upper petals than on the lower ones.
There are five types: 1) single flower; 2) double flower; 3) miniature; 4) cybister; and 5) trumpet. Cybisters have extremely thin petals and are often described as spider-like. Trumpets, as the name suggests, have flared, tube-shaped flowers. Single, double, and miniature bulbs are the ones typically sold by nurseries and other stores for the holidays in December and for Valentine's Day and Easter.
The miniature "Papilio" (which is a species hippeastrum, i.e., not a cultivar or hybrid but the actual plant that grows in the wild) has a unique color and pattern with broad rose-burgundy center stripes and striations of pale green on the upper petals and narrow stripes on the bottom three. "Papilio" has been crossed with both cybister and single flower Hippeastrums to produce hybrids with unusual striping.
