Part of my policy is to only publish photos of my own plants and, sadly, I do not have photos of Coelogyne asperata. The image above is of Coelogyne flaccida and is the background image to all the site's pages.

My plant had not yet flowered after having it for about four years of struggling in a climate in which it is most happy. As a result, I took made a big decision and removed it from my collection. I initially resisted buying one because it grows into such a large plant. It has been cultivated since back in 1849 when Dr John Lindley described in and named it 'asperata' which relates to the rough surface on the lip. Check the flowers out on the following link:

Coelogyne asperata is a large, robust orchid growing over a metre high and having 13cm wide leaves. Beware! It can develop into a couple of hundred kilogram plant. It is  reported as being pollinated by beetles. It can produce up to 30 large fragrant (licorice!) flowers that are an attractive creamy-white colour with many red/brown markings in the throat. "asperata" means rough and refers to the warty lumps on the flower's lip.

Coelogyne asperata is from Malaysia and the Philippines through to the Solomon Islands. Despite the tropical nature of these areas it grows over a huge altitude range from sea level to over 2000 metres and is found on large tree branches or on rocks especially near waterfalls and over streams and at very low levels - i.e. under 500 metres. This probably explains why mine is not happy enough to flower for me. They like a tropical climate ( and they are way too big to be in a normal glasshouse.

Negatives: This is a large plant needing lots of space. In my conditions, this species has been reluctant to flower despite reaching a large size and after several years. Despite being in orchid cultivation for a long time it is not widely grown - probably because it needs so much space and is restricted to warm growing areas.

Rating: ♦♦♦  If you live in a warm climate and have plenty of space then this is for you. Lucky people in tropical areas could simply grow it on a tree in their garden and its size would not be a problem.

Sometimes sold as: Not known

Varieties: None known

Hybrids:

  • 1. Coel Brymeriana (1906) using Coel dayana (now Coel pulverula) as pollen parent. This hybrid is not available in Australia.
  • 2. Coel Memoria Soejana Kassan (1976) using Coel speciosa as the pod parent. It is not available in Australia.
  • 3. Coel Burfordiense (Stanny) (1911) using Coel pandurata as the pollen parent. This hybrid is generally sold as Coel pandurata from which it can difficult to distinguish. However in the hybrid, the side-lobes of the lip are not acute and the mass of molar-like warts on the midlobe are brown rather than cream or white. Coel. asperata imparts the rounded sidelobes and brown warts to its progeny.

4. Coel Siamese T-Rex using Coel mayeriana as the pollen parent (2015 Phil Spence)
