The genus Thunia occurs in India, China, Borneo,  and Southeast Asia.  They were once included in the genus Phaius as the flowers do resemble each other, but there are critical differences.  There are about 6 recognized valid species.
  Thunia alba occurs naturally in North India, Burma, and Thailand.  They bloom from June to August and produce 5-10 fragrant flowers that are about 5 to 6 " across. 
  The plants should be grown in a terrestrial-type potting mix, such as used on Cymbidiums or Phaius.  They should be grown in a shady spot and watered heavily until the leaves fall off.  They should then be kept dry until the new shoots appear in the spring.  At this time they should be watered and fertilized heavily.

  The canes will grow to about 4 feet tall and up to 2 inches in diameter.  Out of the top of the cane is where the inflorescences will appear.  The inflorescence will be short

and pendulous and bear up to 10 flowers.  The flowers will not open all the way but will still be about 5 inches across.  The flowers are slightly fragrant.
  An interesting aspect of this species is that the canes will decompose in the third year as the rest of the plant absorbs the cane and uses it for nutrients.  The canes can also be placed on a bed of sphagnum moss and several plants will be produced from the nodes, but the new plants will not bloom for about 3 years.
  This genus is seldom seen in modern collections, but it can be a very rewarding species to grow.  They are quite easy to grow as long as the rest period is respected.
   This is a good species to grow in a pot, but could be grown outside in a garden in temperate climates. AVAILABLE AT CAMP LOT TROPICALS
