    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 which will develop bright red berries if male Castle Wall blue holly is planted nearby.

    Castle Keep reaches 3-5 feet tall and 3-4 feet wide at maturity. It is hardy in zones 5-7, plant in part to full sun (4+ hours daily). It's best to avoid pruning altogether, as pruning after bloom will remove the potential for fruit to develop. Fertilize with Proven Winners Continuous Release Plant Food in spring. 

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

    1 gallon shrubs are 6-24 inches tall at shipment and quart shrubs are 5-8 inches tall at shipment depending on the season and plant.
