Daniel Mount

Daniel Mount hails from a long line of wandering gardeners, nurserymen and farmers.  He received his first shovel for his second birthday and began his gardening career in the sand box later that afternoon. Spending most of his youthful summers in a vegetable patch, on a farm, in parks, or in the woods, the curiosity of a scientist and the soul of a poet were awakened in him. Daniel went on to study fine arts and botany at the University of Wisconsin-Milwaukee, from which he received a BS in Botany.

Drawn to the legendary gardening climate of the Pacific Northwest, Daniel moved to Seattle, Washington in 1988. Since that time he has created, maintained and consulted on gardens primarily in the Puget Sound Basin. The skills he acquired working in the passionate gardening environment of  Pacific Northwest have opened many doors. Daniel was invited to Cologne, Germany, where he worked on urban rooftop and courtyard gardens as well as rural estates. He was next called to Orto dei Semplici Elbano on the Island of Elba, Italy where he collected and designed with the unique flora of this island.  He maintains an ancillary connection to this garden to this day. Closer to home he has consulted on projects and designed gardens in and around Durham, North Carolina; Milwaukee, Wisconsin and Phoenix, Arizona.

Daniel has settled on a small farm nestled in a 150-acre bird sanctuary, which he shares with his partner, innumerable slugs and a bear, in the Snoqualmie River Valley east of Seattle. He enjoys growing organic vegetables and fruits, raising ducks and experimenting with flood tolerant plants. He creates gardens and also teaches and writes about plants and gardening.
