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.
