Over the years we have befriended many people who enjoy gardening in the shade as much as we do. Some of these friends run nurseries of their own and sell plants that are excellent companions for Hellebores and thrive in similar environments. As you plan your garden and shop for plants, you may want to check out what our friends here have to offer. Each of them sells and ships via their own website.
