This Kingsville saikei has 6 trees. Even number, I know. That only matters in a group planting. The saikei has elements other than the trees. The pot is about 22 inches long.
Years ago, I bought hundreds of Kingsvilles from Col. John Hinds Ret. of Seattle. John was the king of Kingsville on the West Coast.
I had a small time, part time bonsai business and used to vend at various events in California. I gave that up over 10 years ago, but kept a lot of the Kingsvilles for my personal collectrion.
