There are many varieties of heliconia, including smaller heliconia psittacorum types, and other ‘clumping’ types that grow in a cluster. Taken from the Greek word Ἑλικώνιος (helikṓnios), this genus of flowering plant comes from the Heliconiaceae family. The majority of the 194 known species are native to tropical America, with a few variants native to the islands of Maluku and the western Pacific.
Many species of Heliconia are found in tropical wet forests and rainforests, with several of the species being cultivated solely for ornamental use. A few variants are naturalised in Gambia, Florida and Thailand.
This tropical herbaceous plant is part of the zingiberales family, which also includes the bird-of-paradise, bananas, ginger and cannas.

Three quotes on an “Egotist” which I found amusing! Sharing them here on a slide featuring Plumeria obtusa ‘Singapore White’.

Flowers: Flowers are borne in clusters, occurring mainly at the branch tips. Petals are large and waxy, white with a small yellow center. Their fragrance is strong and especially intense at night to attract pollinating moths. In the morning, many flowers drop off. The tree flowers throughout the year in tropical environments. 
In many islands in the Pacific, women can discreetly declare their marital status by placing a Plumeria flower on the right ear if they are single or on the left if they are married. In Hawaii, the flowers are very popular and often placed in floral leis.

Heliconia, derived from the Greek word Ἑλικώνιος, is a genus of flowering plants in the family Heliconiaceae. Most of the known species are native to the tropical Americas, but a few are indigenous to certain islands of the western Pacific and Maluku. Wikipedia. 
Did you know: Common names for the genus include lobster-claws, toucan peak, wild plantains or false bird-of-paradise. The last term refers to their close similarity to the bird-of-paradise flowers (Strelitzia). Collectively, these plants are also simply referred to as heliconias.
