About the genus
Odontoglossum, first named in 1816 by Karl Sigismund Kunth, is a formerly accepted genus of orchids that is now regarded as a synonym of Oncidium. Several hundred species have previously been placed in Odontoglossum. The scientific name of the genus is derived from the Greek words odon (tooth) and glossa (tongue), referring to the two tooth-like calluses on the base of the lip.

In the garden
A member of the genus Odontoglossum within the Orchidaceae, Odontoglossum Thais gx grows as an evergreen epiphyte and is cultivated for its seasonal blooms. In a UK setting it flowers from April to July, so planning for its peak display should focus on a site that limits direct sun and exposure to driving wind. Position the plant in partial shade on a north-facing, sheltered aspect where conditions remain cool and protected. Use a loam-based medium with a neutral pH and ensure the root environment stays moist but well drained; avoid allowing the substrate to become waterlogged while preventing prolonged drought. The plant’s H4 hardiness rating (average) means it will tolerate typical UK conditions but benefits from shelter through colder spells rather than full exposure to frost and icy winds. As an ornamental, place Odontoglossum Thais gx where the flowering period can be appreciated—along a shaded path, within a covered planting niche, or incorporated into a collection of shade-loving orchids. Regular attention to even moisture and a sheltered, north-facing siting will support reliable flowering between April and July, which is when the plant provides its primary seasonal interest.
