My Experience: 

I purchased a 2-gallon plant at Nurseries Caroliniana in March 2011 and planted it in the back behind the garage. It grew steadily, did not burn in the sun and by October 2013 was approximately 3' tall and 15" around. More new growth in 2014 but then one quadrant went brown in late spring. I cut it out and the rest of the plant seemed fine.
