Castle Keep has glossy, leathery, evergreen foliage that makes a handsome choice for landscaping. This is a smaller-than-average blue holly with soft-to-the-touch deep green foliage. This is a female variety that will develop bright red berries if male Castle Wall blue holly is planted nearby.

  • 3-5 feet tall and 3-4 feet wide at maturity
  • Grow in zones 5-7
  • Plant in part to full sun (4+ hours daily)

Care: It's best to avoid pruning altogether, as pruning after bloom will remove the potential for the fruit to develop. Fertilize with Proven Winners Continuous Release Plant Food in spring. 

Pollination: One male plant will pollinate 5-7 females; plants should be located within about 50'/15.24m of each other.
