Have any of you zone 5 gardeners had any experience with Upland Ironweed Vernonia glauca? I want to plant it in a wild flower meadow in Michigan zone 5. However, my acre and a half is encircled by a forest of evergreens and maples and is protected from wind. In the past several years we have not experienced temperatures below minus 10 and the temps rarely go below zero anymore.
I know it has been touted as a zone 5 plant on occasions and I purchased these from a Michigan grower. However, the rather detailed plant tag designates it as zone 6. ARS says it's zone 5. A Google search puts it in zone 6, far below the borders of frosty mid west. These plants will be mulched when planted and watered several times this fall, but then they are on there own. What are there chances?
