(1 review) Write a Review
  • USDA Hardiness Zones 5 - 7
  • Height 5 - 8 Feet
  • Spread 3 - 4 Feet
  • Partial Sun to Full Sun

The Castle Wall Blue Holly by Proven Winners is the male pollinator holly, perfect to pair with other holly shrubs like the Castle Spire Blue Holly. These do not grow berries, but are still evergreen and provide great color year round. The bushes are 5 to 8 feet tall and 3 to 4 feet wide. Plant these in a location that receives at least 4 hours of sunlight per day.

To grow a beautiful evergreen hedge that has 4 seasons of interest, we recommend planting several Cast Spire holly shrubs in a row, and 1 of these Castle Wall shrubs to pollinate the hedge. 1 of these will pollinate up to 5 female shrubs. These are winter hardy in zones 5a, 5b, 6a, 6b, 7a, 7b.

    This was from Proven Winners, so I know it will be a good plant to grow. Can't wait until I start getting some berries. This bush has the typical holly leaves that you would expect. Wonderful plant.
