what zone is an elderberry bush?
I need to know if elderberries will grow in my area, NE Wyoming. The "maps" say we are a zone 3; however, we can hit a couple of weeks in the winter when we do not get above 0.
There are many, many cultivars of elderberry. There are varieties native to most of Europe and North America, and many others have been hybridized in the last 200 years. With some research, you should be able to find some that will grow in your area. Here is an article on basic elderberry growing: https://www.gardeningknowhow.com/edible/fruits/elderberry/planting-elderberry.htm
