Ilex × ‘Blue Boy-Girl’ refers to a duo of evergreen hybrid hollies consisting of a male ‘Blue Boy’ plant and a female ‘Blue Girl’ plant, grown together to ensure abundant winter fruiting. This holly is distinguished by its dark green evergreen foliage with bluish tints, thick and lustrous, highly ornamental all year round. The overall habit is upright, dense, and well-branched, with a silhouette that is taller than it is wide, perfectly suited for evergreen hedges, visual screens, and specimen plantings. In spring, a discreet creamy-white bloom appears, followed in autumn by a generous production of bright red berries on the female plants, providing strong ornamental and ecological interest in winter. Very hardy and tolerant of pruning, Ilex × ‘Blue Boy-Girl’ is particularly valued for durably structuring the garden and offering a four-season display, while serving as a refuge and food source for wildlife.
