My Experience: 

I purchased a 1-gallon plant at Specialty Ornamentals in April 2012 and planted it in the One Of Everything garden. In spring to summer 2013 much of it wilted, probably from poor drainage with the consistent heavy rain we had in June. I dug up some rooted branches and in spring 2014 planted one in the Gumball Border Garden. It died and the original died also. In autumn 2014 I planted a small rooted piece that had been potted in shade all summer in the Octagonal Perennial Garden.
