Winterberry shrubs have female and male plants to produce berries. The Winter Red Winterberry is considered a female plant and needs a male pollinator in order to produce berries. To make it easy, we include a male pollinator plant in this shipment-this plant, Southern Gentleman Winterberry, is smaller and has the same lovely green foliage. Just pair the two shrubs in the landscape, planting them relatively near one another. While the male winterberry produces small white flowers, it does not produce red berries.
