I got this plant last year as a division from a club. It is a division of very old plant and the grower I obtained it from has had it for decades. Grows like a weed. I have my guesses as to what it is but will never know for sure. Enjoy!
The guy I obtained it from has had it since 1980 and got it as a division. I know it is is a cross with a mix of schlimii and longifolium but as to the specific hybrid it is I don't know and don't have a detailed enough knowledge of phrags to be sure. He seemed to think it was a cardinale (sedenii x schlimii) but I think it is either a sedenii or a phrag Calurum (Sedenii x Longifolium). Anyways it is nice to have an orchid that grows and divides like this one does. I have had fun passing divisions on to friends and novices.
