Oeonia
Oeonia is a genus of flowering plants belonging to the orchid family (Orchidaceae). These orchids are native to Madagascar, Réunion, and the Comoro Islands, located in the Indian Ocean.
Oeonia orchids are typically epiphytic or lithophytic, meaning they grow on trees or rocks, respectively, rather than in soil. They are characterized by their often large, showy flowers that are white or cream-colored. The flowers are fragrant, particularly at night, attracting pollinators.
The plants have a sympodial growth habit, meaning they grow horizontally from a rhizome, producing new shoots along the way. Their leaves are typically thick and leathery.
Oeonia orchids are considered to be relatively rare in cultivation and can be challenging to grow. They require specific environmental conditions to thrive, including high humidity, good air circulation, and careful watering.
Several species are recognized within the genus Oeonia, including:
- Oeonia brauniana
- Oeonia curvicaulis
- Oeonia forcipifera
- Oeonia madagascariensis
- Oeonia rosea
Conservation efforts are important to protect these orchids in their natural habitat, as they are threatened by habitat loss and unsustainable collecting.
