Hello: I hope someone can answer this. I have been scowering the web for many hours re: this beech issue for the above cultivars. Very confusing. Seems like I'm onto something at this forum though! I have what the nursery said was 'roseomarginata'. I live in zone 5 Ontario. It always has been very deep purple with only a slim pink margin and very little white. It has not changed since I bought it two years ago. However, I have seen in Marion Jarvie's garden (Canadian Horticultarist), a few 12-15 ft specimens that are VERY pink, fairly white and some dark green. Her trees look very different. She says it is 10 years old. Is this then the infamous Tricolor? I recently purchased at the nursery she recommended another 'tricolor' beech. This 3 foot tall specimen is VERY pink, a bit of white and green like Marion's. Will this become 'roseomarginata' in style or could I in fact have the real mccoy?
