Do you have them in pots for decorative reasons? Cuz they're really hardy in ground...at least in MN (4b) I had 'White Swan' last a few years until it got some virus and became distorted.
The 'PowWow Wild Berry' is a test here. I gave plants to several different gardeners. Some in containers, some in ground. You see, Echies aren't native here and don't like our summer humidity, at all, at all, so no one has had any luck growing them. If they make it thru July-August, possible 6" rainfalls and a potential hurricane, then we'll have an Echie down here.
Will take photo when it opens. Might even try to use my new camera that has more knobs and dials than a fighter jet plane. Well, it does have ZOOM
