I have Bambusa ventricosa 'kimmei'. It is a clumping bamboo. The shoots emerge green and turn yellow soon after with green stripes. When grown in a pot under dry conditions it becomes dwarfed with swollen internodes. In ground it grows straight, but new growth will revert to dwarfed when stressed in a pot. Max height is ~55' with ~2.3" diameter canes.

This is the actual division.
This is the root ball when I took the division in May of this year.
This is my plant.
Let me know what you have to offer. I'd love an AEAE.
I can take other larger divisions for someone local, but will only ship smaller ones.
