A orchid in my collection is labeled c. Esbetts 'Blumen Insel'. There is no grower name on the back of the tag but it's listed as a white.
When I do a search for this flower, I get 'Lc' not cattleya. Also I get Lc Esbetts CLOWN 'Blumen Insel' which is a white with yellow flares, very nice.
The wording or lack of wording on this tag has me a bit confused.
