This orchid, Cattleya skinneri, was bought 30 years ago. The name has been changed in the last 5 years to Guarianthe skinneri. The purple flower looks like the wild ones in the jungle.
This is also a Guarianthe skinneri but it's been changed by man. This species rarely have white flowers. This is also my favorite picture of last year. Click here to view thumbnails for all participants
