Good afternoon. Can somebody tell me what is the plant that is used as a backdrop for the bonsai at exhibitions. It is located next to the tree on a separate stand and sometimes has the most unusual shape and form.

It is referred to as accent plant

It's called "kusamono". Bonsai Empire answered me in facebook. Thank you, Bonsai Empire.

That is a very specific artstyle, not specifically used for bonsai accents, but could be applied.

I believe it is called kusamono if it is being displayed by itself and shitakusa if it is used as an accent. Let me know if I have that confused.
