Uses Notes: 

Broad columnar shrub that is great as a foundation, specimen or hedge plant. Good in groupings and mass plantings. Makes a good screen. Good for winter gardens.

Maintenance Notes: 

According to the Humane Society of America Ilex berries can be toxic to pets. This is means that the plants are generally identified as having the capability for producing a toxic reaction.

Prune to shape immediately after flowering. Likes high moisture. Native to swampy and boggy areas. Adaptable to wet soils, does well in light and heavy soil. Fertilize in early spring by applying a slow release fertilizer specialized for trees and shrubs. Follow the label for recommended rates of application. Protect from winter wind and sun in cold (Zone 5) climates. Use as a pollinator for Castle Spire holly.

The Castle Ilex are compact, pyramidal varieties of blue holly. Dark glossy leaves, superior vigor and branching make them an improvement over other older varieties. Their narrow form makes them great for hedges, foundation plantings, or even as a dramatic specimen. The lustrous green foliage provides season long interest. Use Castle Wall holly as the pollinator for Castle Spire holly, or grow it on its own as a narrow hedge.  This is a male variety that will not produce fruit.
