Dendrobium unicum Seidenf. 1970 is a colourful miniature orchid species native to Thailand, Laos, Myanmar (formerly Burma) and Vietnam. The bright orange Dendrobium unicum flowers look quite similar to Dendrobium lamyaiae Seidenf. 1996, with the exception that the lip of Dendrobium unicum is straight-lined, while Dendrobium lamyaiae is curly. The fragrant Dendrobium unicum flowers reach a size up to about 5 cm. Flowering period: February - May. Dendrobium unicum orchids are protected by CITES Appendix II (trade controlled to avoid use incompatible with species survival).

The tropical miniature orchid requires cool to warm temperatures, a medium amount of light and a well-drained potting medium. Plants should be kept humid, but not wet during the growth season. During dormancy, starting in late autumn, waterings should be restricted until new growth appears in spring.
