Calanthe Sedenii was registered in 1878 by Veitch as a hybrid of Calanthe Veitchii and Calanthe vestita. There are different clones of Calanthe Sedenii, the one we grow in our collection has big pure white flowers and was sold as Calanthe Sedenii ‘Harrisii’. It is a Preptanthe that drops it leaves in winter. The inflorescece is formed at the bottom of the naked pseudobulb. We do not water for about three months until the new growth forms.
The shape of the lip is a heritage of Calanthe rosea
