This is my Seiju, I've had it for about two years and I made the first cuts on it this past winter. It was purchased from the Muranaka nursery in Nipomo, CA. It was propagated from a root cutting about 5 years prior to my ownership.

Won in a raffle ($1.00) as a tall skinny whip in 1991.
Air layered top 2/3rds off in 1998. Mostly in the ground until 2003.
Now 13 inches tall, I am working on thickening a back branch and working on the lower right mass of stuff.
