We grow the Juniper in lava-rock (pumice stone) by boring a hole in the rock and sawing flat the bottom of the stone. Since the lava-rock is pourous the rock serves the same purpose as the bonsai pot. When we think of a traditional bonsai and what it should look like we think of a Juniper procumbens. They are hardy and long-lived and tolerate many adverse conditions. Popular and Unique. 5 years old 12″ - 14″ tall. Suitable 12″ round humidity tray is recommended. To purchase add .00. Shipped via UPS 2-3 days - .95.
