Well Michael is doing all this work posting so many nice cultivars, let me give a hand ;o). This cultivar, Bi hoo, is an introduction by ganshuku /masayoshi in 1993, however I do not know the lineage. I have seen the name also translated as Bihou or Bi fo. Its main interest seem to be the bark colour: orange-yellow, but I also find the leaves to have nice yellow tones in late summer (pics taken first week of September). It is a very vigorous plant and, where I bought mine, I saw 4 year old specimens more than 2 meters high .
