It was introduced to European gardens in 1736. The fruits are highly ornamental and edible to birds and wildlife. Garden historian Ann Leighton believes this is the "Red Berry" George Washington looked for when riding out to find movable shrubs and trees for Mount Vernon. The shrub was initially given the name Prinos verticillatus by Carolus Linaeus, indicating that this is the species Philadelphia nurseryman Bernard McMahon listed as "Ilex prinoides -Deciduous Holly" in The American Gardener's Calendar, 1806. "Winter Red" is the female plant and requires a male plant, such as "Southern Gentleman" for sufficient pollination to produce red berries. zone3,zone4,zone5,zone6,zone7,zone8,zone9
