Castle Spire® Blue Holly commands attention with its ultra-narrow, pyramidal form and glossy, dark green foliage. As a female variety, it brings seasonal interest with bright red berries when paired with a male pollinator like Castle Wall®—but even on its own, this evergreen stands tall as a striking architectural feature in the landscape.

Its dense branching creates a lush, full silhouette that resists winter damage by limiting wind penetration. This natural durability, combined with a manageable height, makes Castle Spire® an ideal choice for hedging, screening, or planting near buildings where space is limited but impact is essential.

Reliable, elegant, and visually bold, Castle Spire® delivers year-round structure and drama with minimal maintenance—perfect for modern landscapes that demand both beauty and resilience.

  • 8-10 feet tall and 3-5 feet wide at maturity
  • Hardy in zones 5-7, be sure to check your USDA zone to ensure success
  • Plant in part to full sun (4+ hours daily)
  • Space plants 3-5 feet apart for best results
  • Produces white flowers in the spring and red berries in the fall if planted near a male pollinator
  • Maintains soft to the touch, glossy deep green foliage year-round
  • Attracts bees
  • Blooms on old wood
  • Great for borders, hedges, edges, screening, landscapes or mass planting 
  • Fall and winter interest

Care: Fertilize with Proven Winners Continuous Release Plant Food in spring and mid summer. It’s best to avoid pruning, as flowers grow from old wood. If you need to do a few maintenance cuts, you can do so in the late winter or early spring.

Pollination: This is a female variety. It will need a male pollinator to produce berries. Plant one male for every seven females, and be sure to position them within 50 feet of each other so they can get good cross-pollination.
