I’ve sung the praises of white valerian (Valeriana officinalis) in the garden many times on this site and in public presentations. It’s one of the most impressive perennials I grow in my community garden plot. Although it isn’t directly useful as an edible like most of the other perennials I’ve put in, it does good things for the garden. We are continuously impressed by it’s beauty, size, smell, and ability to attract beneficial insects.
