I'm looking for anybody in Canada who has a very tall species of grass named either Saccharum arundinaceum or Saccharum procerum or Erianthus procerus - depending on who is naming it. It is supposed to be cold-tolerant to plant zone 6. These nurseries call it "Saccharum arundinaceum": Bluestone Perennials ( http://tinyurl.com/qfbp5ca ) and Plant Delights (http://tinyurl.com/ndywe9c ) carry it in the USA. This is not Miscanthus giganteus, nor is it the plant variously named Saccharum ravennae or Erianthus ravennae or Ripidium ravennae. I have these in my garden already. Help!
