Thoughts?
Love the ume's by the way.
Yamadori for all species are found trees and they do have a natural character unsurpassed by plants we grow ourselves.
Prunus Mume are difficult and unreliable, many species are easier to work with.
Older plants and Yamadori of most species require grafting if taken to the highest levels.
We will never find older plants that have been cultivated for a very long time in North America if we do not grow them here!
They would not be "found" in Japan if growers had not faced the difficulties in growing, maintaining and developing the species. Not sure if there is anything new or startling about this information. This can be said for mature landscape material world wide and mature container grown material world wide.
Appreciating high level trees and striving to attain that involves an understanding of the above, not an approach that we should not do it, or strive to match the success that others have achieved.
The number of wild collected Yamadori or found trees is shrinking in Japan and most countries for a number of factors. I would argue that it is even more important to tackle the difficult species if we wish to continue working with them in Bonsai.
Seems like a mixed message to me. On the one hand the claim is the goal is to take Bonsai to the highest level, on the other hand the message seems to be if it is difficult leave it to those who have already mastered it.
I hope not all teachers discourage reaching for difficult achievments.
