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.
