Features

Characteristics

Plant Needs

The Castle Spire® Blue Holly brings timeless beauty and structure to the garden with its strongly pyramidal, upright form. Part of the Castle™ series, it offers dark, glossy foliage, vigorous growth, and superior branching, making it a standout choice for foundation plantings, hedges, or even as a single specimen.

As a female variety, Castle Spire® sets an impressive crop of bright red berries in fall and winter when paired with its pollinator, Castle Wall® holly. The combination of lustrous foliage and brilliant berries ensures year-round interest.

Why we love it:

  • Its compact, narrow habit makes it versatile for hedges, screens, or accents.

  • Glossy evergreen leaves provide four-season beauty.

  • Berries galore (when pollinated) add brilliant winter color and feed wildlife.

  • Strong vigor and branching make it more reliable than older holly varieties.
