Hardiness zones confusion
We are near Sunriver and have believed our hardiness zones to be 3-4. I admin an online gardening group and the newer USDA zones show us as 5B. We can get as cold sometimes as -20. Nursersies still follow the zone 3-4 language. What do I tell the group? There’s much confusion on this topic.

It is still suggested that gardeners purchase plant material for USDA Hardiness zones 3-5 in the Sunriver area. Here is a publication that you can refer people to that can further explain it.
