Description

The Castle series brings compact, pyramidal forms to the world of blue holly. Their dark glossy leaves, superior vigor and branching make them an improvement over other older varieties. Narrow form makes them great for hedges, foundation plantings, or even as a dramatic specimen. The lustrous green foliage provides season long interest. Castle Spire® is a female variety with a strongly narrow, pyramidal habit. Sets abundant fruit when pollinated by Castle Wall® holly.
