Generally, plants that are in stock will be shipped within a week after your order is received.
Once it has shipped you will receive an email with your FedEx tracking number.
Occasionally plants may be trimmed before shipping to ensure fuller branching and flowering in your garden.
Very attractive color and form.
Castle Spire is a regal accent for your landscape! Dark glossy leaves, superior vigor and branching make it a superior choice over other varieties. Narrow habit makes it ideal for hedges, foundation plantings, or even as a dramatic specimen. Lustrous evergreen foliage provides year-round interest. Castle Spire® will produce bright red berries if planted near a male pollinator like Castle Wall® blue holly. Fruit is not edible.
Great as a foundation plant, specimen or hedge, can be used as a replacement for pyramidal yews. Good in groupings and mass plantings, perennial and shrub borders, can be used as a screen or hedge. An outstanding plant for the winter landscape.
Castle Spire® holly is a female variety; a male variety, like Castle Wall®, must be planted nearby in order for fruit to form. One male will pollinate 5-7 females. Plant within 50'/15.25m of each other to ensure pollination.
It's best to avoid pruning female hollies, as cutting them back at any time of the year will result in diminished flowers and subsequent fruit. Light trimming or removal of dead wood can be done in early spring.
Holly prefers acidic soils with average moisture and appreciates a good layer of mulch. If desired, apply a granular fertilizer formulated for trees and shrubs in early spring.

I have had this plant growing on a northern exposure in front of a covered porch here in southern zone 5A. It went through a very cold winter with no noticible damage and is getting ready to grow beautifully.Seth HenryIllinoisUnited States5 years ago
