Ilex verticillata, commonly known as Winterberry or False Alder, is a deciduous holly known for the densely packed, bright red berries it displays in mid-winter. The combination of bare branches and these bursts of winter color make Winterberry a distinctive ornamental species in nearly any landscape. Winterberry will grow in the average garden without any trouble. It flowers and fruits best in full sun. The only real dangers for Winterberry are drought and alkaline soils. Winterberry is an excellent border shrub and looks its best when planted in mass.
