Matthew Roberts - Store Manager and Horticulturist


Grew up in the Deep South in a small house with a big garden created by an LSU horticulture professor. His parents watched from the air-conditioned solarium as he learned how to mow (and weed & prune & fertilize & transplant). He received his BA  and moved way up north to DC and promptly discovered he preferred digging in the dirt to designing buildings. It took all the combined wisdom of his MLS from G’town to figure out how to do that for a living and joined the crew at Ginkgo the year that it opened. After completing his Master Gardener work hours at the British Embassy gardens in Northwest he concentrates on his five thousand square foot roof garden overlooking Rock Creek and the National Zoo which he shares with his husband Michael, their dog Kip and their cat the Shadout Mapes. After an agonizing internal debate attempting to pare down his list of favorite plants to a single choice; he balked and had to deliver: dahlias, perennial hibiscus, and hyacinth bean vine!
