Give Edgeworthia A Try In Your Winter Garden

To begin, I must thank South Carolina nurseryman, Mr. Ted Stephens, who gifted me a Chinese paperbush (Edgeworthia chrysantha) 12 years ago.

Shagbark Hickory

Most tree lovers don’t plant U.S native shagbark hickory (Carya ovata) (USDA hardiness zones 4-8). Instead, they often inherit one when purchasing property.

Like oaks (Quercus spp.) and beeches (Fagus spp.), hickories are long-lived, often standing tall in an open […]
