it will tolerate a little semi shade but will do better in sun. the rhizome needs to be half on the surface and half buried. I would dig in some grit with it before planting, just to help drainage. They are easy and relatively trouble free, in my garden any way. I have a deep purple one called 'black'.
hope this helps.

And try to plant the rhizomes with the leaves at the North end , so that they do not keep the sun off the roots.
