Thunia alba (Lindl.) Rchb. f. 1852


Thunia alba (Lindl.) Rchb. f. 1852 is a terrestrial, occasionally lithophytic growing orchid species with highly fragrant flowers. Thunia alba orchids are native to the Himalayas, India (Assam, Sikkim), China, Nepal, Bhutan, Myanmar (formerly Burma), Thailand, Vietnam and Malaysia. Flowers get a size of about 8 cm in diameter and are not opening well. Flowering period: June - August. Thunia alba orchids are protected by CITES Appendix II (trade controlled to avoid use incompatible with species survival).

The tropical ground orchid requires intermediate - warm temperatures and a shady location. Plants should be watered and fertilized heavily until the bamboo-like leaves drop in autumn, then waterings and fertilizings should be restricted until new growth appears in spring. Thunia alba needs a very dry winter rest, the orchid will not bloom, if this isn´t respected.
