About the Castle Wall® Blue Holly
Castle Wall® Blue Holly (Ilex x meserveae ‘Heckenstar’) is a majestic columnar evergreen shrub that adds regal elegance to your landscape. This male holly variety is a stellar choice over others due to its superior vigor, glossy dark leaves, and exceptional branching, ideal for hedges, foundation plantings, or as a striking specimen. Although this male holly does not produce fruit, it serves as a pollinator for female varieties like Castle Spire® and Castle Keep®, enabling berry production for several female plants.
With a moderate growth rate, reaching a mature height of 5 to 8 feet and spreading 3 to 4 feet, the Castle Wall® Blue Holly boasts a narrow pyramidal form, making it an excellent choice for landscape accents. Its dense growth habit and glossy, dark green foliage provide year-round visual interest, while its upright structure makes it a standout choice for formal gardens or focal points.
Growing Castle Wall® Blue Holly
Easy to maintain with little pruning needed, its natural columnar shape stands out without significant trimming. Thriving in average, slightly acidic, and well-drained soils in full sun to partial shade, the Castle Wall® Blue Holly is hardy in USDA Zones 5-7.
This evergreen grows best in locations protected from harsh winter winds, and appreciates moderate watering and a layer of mulch. Known for its excellent winter hardiness and resistance to pests and diseases, this holly adds both charm and practicality to your outdoor space. Elevate your landscape with the distinguished beauty of the Castle Wall® Blue Holly, a reliable and low-maintenance choice for creating stunning hedges, foundation plantings, or dramatic focal points in your garden.
