More than three dozen species of Heliconia have entered the cut flower trade since the expanded interest in bold tropical cut flowers began in the early 1980s. Most were wild-collected originally with little information on their habitats or season of bloom. A natural flowering season for some species can be found in the taxonomic literature, but it may be influenced locally by rainfall and drought periods as well as by photoperiod and therefore not reliable in indicating production periods in Hawaii. Sales records from 1984 through 1990 or several heliconia growers on Oahu reflected not only the quantities produced but also the time and duration of the blooming season. Such information is helpful in coordinating with the flower markets. Heliconia species of commercial interest with strong seasonal flowering periods are noted: angusta, bihai, caribaea, caribaea X bihai, collinsiana, farinosa, lingulata, rostrata, sampaioana, stricta, subulata, wagneriana.
