Cuphea Epilobiifolia

''Cuphea'' is a genus containing about 260 species of annual and perennial flowering plants native to warm temperate to tropical regions of the Americas. The species range from low-growing herbaceous plants to semi-woody shrubs up to tall. Commonly they are known as cupheas, or, in the case of some species, as cigar plants. The generic name is derived from the Greek word κυφος (''kyphos''), meaning "bent," "curved," or "humped."

Uses

Several ''Cuphea'' species are popular ornamental plants or honey plants. '' C. ignea'' 'David Verity' and '' C. micropetalia'' are popular plants to attract hummingbirds.

Some species of ''Cuphea'' are used to produce cuphea oil, of interest as sources of medium-chain triglycerides. For most purposes, cuphea oil is identical to coconut oil and palm oil; these are derived from strictly tropical plants however and – particularly in the latter case – the expanding production of which has caused a considerable amount of habitat destruction. ''Cuphea'' may thus produce a valuable source of income for farmers in temperate regions, and by supplementing coconut and palm oil to satisfy the growing demand (e.g. for biodiesel production) at the same time decreasing the need for wholesale logging in tropical countries. Early attempts at commercial production have focused on an interspecific hybrid population derived from '' C. lanceolata'' and Clammy Cuphea ('' C. viscosissima'').

''Cuphea'' has also been shown to improve agricultural crops in North America when used in crop rotation. Crop rotation is commonly practiced among farmers to improve soil quality, control host-specific pests, and decrease the use of fertilizers and pesticides. When cuphea was introduced into the crop rotation of corn and wheat, scientists from the Agricultural Research Service of the USDA found that the addition of ''cuphea'' had positive effects on the following harvest, including a higher yield of crop and crops that are higher in protei

Such research reveals how ''cuphea'' can be used in agriculture to increase the profitability of crops like wheat and corn.

The seed oils of some species are very rich in one particular fatty acid. '' C. painteri'' oil, for example, is about three-quarters caprylic acid; '' C. carthagenensis'' oil consists of about 80% lauric acid. '' C. koehneana'' oil may be the richest natural source of a single fatty acid, with 95% of its content consisting of capric acid. Currently the plant is not commonly used for medicinal effects; however, chemical analysis of its fatty oils suggest the plant could possibly serve as an algicidal, fungicidal or antibiotic agent. There is also reason to believe the plant could be effective as an appetite stimulant.
