Handsome columnar holly.

Castle Wall® holly is a regal accent for your landscape! Dark glossy leaves, superior vigor and branching make it a superior choice over other varieties. Narrow habit makes it ideal for hedges, foundation plantings, or even as a dramatic specimen. Castle Wall® holly is a male variety that will pollinate Castle Spire® and Castle Gold holly, but it does not produce fruit itself.

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: 

Castle Wall® holly is a male variety that does not get fruit but will serve to pollinate female varieties, like Castle Spire® and Castle Gold holly. One male will pollinate 5-7 females. Plant within 50'/15.25m of each other to ensure pollination.

Male holly like Castle Wall may be pruned after flowering if desired, but its natural columnar habit should need little trimming.

Holly prefers acidic soils with average moisture and appreciates a good layer of mulch. If desired, apply a granular fertilizer formulated for trees and shrubs in early spring.
