Little did I know when I purchased this single growth plant a few years ago that it was probably deflasked in the 1980s. So that makes this, still, single growth plant at least 30 years old. As the label shows its originally from the Eric Young Foundation. Their stock number was 8890 - if anyone has more info I would appreciate it. Its a roth 'Mont Millais' cross. I wonder how long until it flowers again........
