Ilex x meserveae ‘Hachfee’ Castle Spire® Blue Holly
The Ilex Castle Spire® is handsome year-round and spectacular when laden with fruit. This variety of dwarf, pyramidal, blue holly is an introduction from Germany from a cross of Ilex aquitolium ‘Pyramidalis' and Ilex x meserveae 'Blue Prince'. The most noticeable improvement for this Proven Winners® selection is the symmetrical branching and shiner leaf. It makes a great foundation or hedge plant, or a dramatic statement as a specimen plant.
This holly has a dense, narrowly upright, columnar habit that makes it relatively low maintenance. In the St. Louis, Missouri area it flowers in May. It responds well to pruning, but one may sacrifice berries if pruned too hard. If needed, the best time to prune is late winter, after the threat of extreme cold has passed. Use the male Ilex x meserveae 'Heckenstar' Castle Wall® as the pollinator. The berries on Castle Spire make this plant a good choice to attract birds to your yard in the winter. A sprig of foliage will embellish a holiday wreath or centerpiece.
The Castle series of holly is a pest and disease resistant shrub. It is easily grown in average soil that is slightly acidic and well drained in full sun to part shade. Keep soil evenly moist, although it does not tolerate soggy conditions. In USDA Zone 5 it may grow best in a location sheltered from harsh winter weather and with a protective layer of mulch on the root zone. Fertilize in early spring with a slow release fertilizer formulated for trees and shrubs.
