There is more to it than simply your planting zone. Your microclimate and climate have a lot more to do with success than simple winter temperatures.
Zone 5 sounds exactly right for these plants, but like I said, there are no guarantees. Soil type, the moisture level going into winter, yada yada yada all play a part.
If you live in an area with scouring winds in winter, that can impact newly planted shrubs.
It also depends on if your plant is bare root, or in a pot. If it’s bare root and dormant, it will need to be watered when you first plant it, then any time you don’t get rain for the first six months to a year.
If potted, water well, then occasionally throughout any hot and dry periods.
I would consider them established when they come through their first winter and grow successfully. Sometimes the new grow will emerge, but there is root damage or the bark has sloughed off and the plant will die.
