My Experience: 

I purchased a 1-gallon plant from Nurseries Caroliniana in May 2010 and planted it on the left property line near the Jade Snowflake Chinaberry in the 'Big Trees and Birds' garden. It grew steadily, with two main branches. The one day I noticed that the leaves looked like they were in whorls. Closer examination revealed that one of the two stems had started to grow in a spiral, not gaining height but wrapping around with 4 coils already. The leaves were growing in a bunch from the stem. I tried to open it up but the wood was too stiff so I ended up cutting it off. Not much growth since then! Sometime in the last 2 years it has grown and is now about 4' tall, still mainly 2 stems but starting to flesh out in May 2012.
