Because I posed this, I have been going though my gafu ten books. this is the Shohin competition run by the Japanese Shohin association.
Majority of the trees that set the display IE the tree sitting at the top of the rack, are 20cm there are some exceptions. There is one that is 20cm with a jin going another 20cm. So the apex is the foliage, not the jin.
Mame and Shohin have different heights, but they have no definitive starting point. Mame 15cm Shohin 23cm, a mini class of trees at 10cm or less, which has been in the past the starting point for Mame. All measurment taken from the rim of the pot.
There were also 8 root on or over rock trees, two of them the rock was very dominant.
The western world with its need for rules, have defined what we now see. In competition it is up to the show coordinator, or the club to set the limits.
Providing these are set before hand, there should not be a problem.
These are what I have gleened over the years as my trees get smaller, but I am not worried too much by this, need for the ugh rules.
I just enjoy making them, by the way is that a challenge that it cant be done in 18 months.
Cheers Pup
