Castle Wall has dark glossy foliage year-round and white spring flowers. Castle Wall holly is a male variety that will pollinate Castle Spire and Castle Keep holly, but it does not produce fruit itself. Narrow habit makes it ideal for hedges, foundation plantings, or even as a dramatic specimen. 

Castle Wall reaches 5-8 feet tall and 3-4 feet wide at maturity. It is hardy in zones 5-7, plant in part to full sun (4+ hours daily). May be pruned after flowering if desired, but its natural columnar habit should need little trimming. Fertilize with Proven Winners Continuous Release Plant Food in spring and mid-summer.
