which azaleas are winter hardy
There are a few azaleas that are considered hardy, but in truth, most are not. There is a series called Northern Lights that were developed to take the cold, but they won't survive in your region. I live in a region similar to yours and there's really no reliable azaleas. PJM rhododendrons will survive in your region if you plant them in a protected spot, but I think you might want to select another, more hardy genus for your garden.
