He writes regularly for national gardening magazines such as Fine Gardening and Horticulture, and is a repeated guest on NPR's Splendid Table and popular gardening podcasts such as A Way to Garden. Joseph is the author of Plant Breeding for the Home Gardener and Rock Gardening, and he gives gardening presentations to audiences across the country. He lives with his husband, two cats, a dog, and an absurd number of plants in Williamsburg, Virginia.
