We acquired four plants from a release by National Geographic in 2005. Two are in the ground and two are held back -- just in case. So far the plants have survived 13 degrees on the low side and the upper 90s on the high side in typical Georgia clay.We saw an 8 foot tall specimen in Oregon and it was quite striking with tiered branching on a very rigid main stem. Our experience so far is only with the juvenile forms of this plant. How it will prosper in Georgia going forward remains teo be seen, but so far, so good.
Planting instructions from the Geographic suggested a well-drained planting site with protection from temperatures below the mid 20s and a fertilizer application low in phosphorus. the plant should spurt and grow to 20 feet in ten years.
