My Experience: 

I purchased 20 rhizomes from Lowes in March 2011. I planted 5 in the cutting garden and 2 in the courtyard, 6 in the berm and 3 in the perennial bed, 1 in the One of Everything garden and the rest...

It turns out rabbits love the leaves and if the stems get big enough, deer then cut the flower stalks off. In 2014 I tracked down the remaining plants: 1 in the One Of Everything garden, 1 in the Pool Lawn Border.
