Castle Spire has dark glossy foliage year-round and white spring flowers. Castle Spire will produce bright red berries if planted near a male pollinator like Castle Wall. Fruit is not edible. Narrow habit makes it ideal for hedges, foundation plantings, or even as a dramatic specimen.
Castle Spire reaches 6-10 feet tall and 3-4 feet wide at maturity. It is hardy in zones 5-7, plant in part to full sun (4+ hours daily). Fertilize with Proven Winners Continuous Release Plant Food in spring and mid-summer.
Pruning: 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 deadwood can be done in early spring.
