In a previous post (Beyond Begonia grandis: new hardy begonias), I discussed several begonia species and hybrids that have been around for a few years and were already known (or purported) to be fairly hardy. In this post, I'll discuss a new generation of begonias I've discovered to be hardy in my zone 7a/b garden in just the last few years, even though some of them have been around much longer than that!
