"While the story/ad sounds like hype, there are some things not mentioned that really could make the Bardsey apple unusual. First, is the old tree a seedling or was it asexually propagated? I say it that
way because it wasn't that rare to layer an apple tree, or even start it from root cuttings of a seedling, in addition to the possibility of being grafted. That one tree could have been a lone survivor of a
group of them."
So what you're saying is that this is an important tree because it might very well be an important tree if we only had some more information. How can any important cultural history ever be tied to this tree if so little is known about it? Why should it be important until that information is actually known? It's not in a part of the world where people are exactly starving for historical artifacts.
I'm sorry if this sounds like quibbling and I realize that this is an argument of no importance. I just can't help myself, I love to quibble.
