Panicum virgatum 'Hanse Herms' German speaker needed
I've dug up and potted an established clump of this grass and I'm wondering if I should protect it over winter. I've done a web search re hardiness and just about everything is in German. My German is more or less nil.
Can someone help me out here please either from personal experience or doing the search on my behalf.
