Holly shrubs in 15-gallon containers are well-established specimens that provide immediate visual impact. These evergreen or semi-evergreen plants are prized for their glossy, deep-green foliage—often with spiny or serrated leaf edges—and their decorative berries, which range in color from bright red to orange, yellow, or black depending on the variety. They are ideal for use as privacy screens, foundation plantings, formal hedges, or standalone specimen plants. Mature hollies in this size typically range from 3 to 8 feet in height and 3 to 6 feet in spread at the time of sale, with continued growth depending on the variety.

Holly shrubs thrive in full sun to partial shade and prefer slightly acidic, well-drained loamy soil. They are generally drought-tolerant once established and are known for being deer resistant and tolerant of urban pollution. Fertilizer is typically unnecessary; an application of mulch around the base helps retain moisture and regulate soil temperature. If pruning is desired, the best time is in late winter or early spring before new growth begins. Most holly varieties produce small white spring flowers that give way to ornamental berries that persist through winter, providing year-round seasonal interest and attracting birds to the garden.
