Cuphea

Cuphea is an accepted genus of flowering plants native to the Americas, with species ranging from herbs to subshrubs and shrubs. Their growth form, mature size, flower display, and climate needs vary widely, so care should follow the identified species or named selection. ## Range and garden use Kew places Cuphea in the loosestrife family, Lythraceae, and describes the genus as including herbs, subshrubs, and shrubs with tubular flowers that are often brightly colored. Some cupheas are grown as compact flowering plants, while others develop into larger, woody forms. That diversity means a single height, spread, or tolerance should not be assumed for every member of the genus. Identify the plant as precisely as possible before choosing a site or applying species-level care advice. The [Kew Plants of the World Online genus profile](https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:30000193-2/general-information) summarizes accepted taxonomy and the genus range. For a cultivated cuphea, use a source that matches its exact species or product name. ## Maintenance Match watering, light, pruning, and winter protection to the identified cuphea rather than treating all members as having the same requirements. Many garden forms benefit from well-drained soil, but verify that guidance for the plant being grown.
