Do you have particular plant groups you like more than most? Because of family history or where you live, perhaps? The Geranium family of flowering plants rank right up there for me. And I’m not alone. This week on Cultivating Place we’re joined by Robin Parer — founder and owner of the specialty Geraniaceae Nursery, champion of all members of the Geraniaceae family. She is also the author of “The Plant Lovers Guide to Hardy Geraniums,” out now from Timber Press.
