Long a favorite during its evaluations, Castle Keep® blue holly has the classic good looks of this handsome evergreen but with soft-to-the-touch deep green foliage. Semi-dwarf rounded habit makes it a versatile choice for landscape. This is a female variety that will develop red fruit if a male pollinator like Castle Wall® holly is planted nearby.

General Care
Soil Prefers moist, acidic soils. Shallow root system benefits from mulch.
Pruning Blooms on old wood; however, it's best to avoid pruning female hollies as pruning after bloom removes any developing fruit.
Uses Hedges; screens; specimen; landscaping.
Growing Tips Plant a male pollinator within 50' to ensure pollination; one male will pollinate up to 7 females. To minimize winter damage to the evergreen foliage, provide late-season irrigation if necessary and site so that plant is protected from harsh winds and sun.
