With glossy, leathery, evergreen foliage, Castle Keep® blue holly makes a handsome choice for landscaping. This is a smaller-than-average blue holly, growing just 3-5' tall and wide, and with soft-to-the-touch deep green foliage. This is a female variety which will develop bright red berries if male Castle Wall® holly is planted nearby.
Top reasons to grow Castle Keep holly:
- Semi-dwarf habit is easy to use in home landscapes.
- Dark evergreen foliage lends handsome good looks year-round.
- Dense, rounded habit needs no pruning to keep a nice shape.Foliage InterestWinter Interest

With its neat, rounded shape, Castle Keep holly could make a nice alternative to boxwood in containers and formal settings. It also adds texture and year-round color to landscapes and gardens.Maintenance Notes:
It's best to avoid pruning altogether, as pruning after bloom (which would normally be the appropriate time on plants that bloom on old wood like this) will remove the potential for fruit to develop. Fortunately, with its dense, rounded habit, little pruning should be required.
This female selection requires a male variety in the vicinity to develop fruit. One male will pollinate 5-7 females; plants should be located within about 50'/15.24m of each other.Castle Keep® Ilex x meserveae 'SMNIFA' USPPAF, Can PBRAF
