This week I visit Dean Norton, Director of Horticulture at George Washington's Mount Vernon (@ 5:47) and recommend Andrea Wulf's 'Founding Gardeners' in The Play List. The Plant of the Week really has nothing at all to do with the General, I cannot tell a lie, but it is a versatile and useful plant that I am propagating the heck out of these days, in order to improve my garden once the dog days wane.
