I know .. it isn't fair that I tricked you with that title .. made ya' LOOK ! haha Avalanche is a Calamagrostis as Karl Foerster .. only with variegation. I know I said that Karly Rose is my favorite ornamental grass .. but Karl and brother Avalanche are also staples in my garden. I love the contrast these grasses create just by "standing" next to perennials .. I have quite a few different ones squeezed in my zoo and I love each and every one for their unique personality !
