Ilex aquifolium 'Alaska', commonly known as Alaska Holly, is a specific cultivar of English Holly (Ilex aquifolium) that is valued for its distinctive variegated foliage. Here's a short description including its maximum height, care instructions, and hardiness:
Maximum Height: Alaska Holly typically grows to a height of 10 to 20 feet (3 to 6 meters), although it can be pruned to maintain a smaller size.
Care Instructions:
-
Sunlight: Alaska Holly thrives in partial to full sunlight but can tolerate some shade. However, for the best variegation (white-edged leaves), it benefits from more sunlight.
-
Soil: Plant Alaska Holly in well-draining, slightly acidic to slightly alkaline soil. Ensure the soil remains consistently moist but not waterlogged.
-
Watering: Water regularly, especially during dry periods, to maintain consistently moist soil. Adequate watering is essential, especially when the plant is establishing itself.
-
Pruning: Prune as needed to control size and shape. Alaska Holly responds well to pruning and can be used in hedges, as a specimen plant, or in formal garden designs.
-
Fertilization: Use a balanced, slow-release fertilizer in the spring to provide essential nutrients. Avoid excessive fertilization, as it can lead to rapid growth and reduced variegation.
-
Berries: Alaska Holly may produce berries if both male and female plants are present. Male hollies are typically used for pollination.
Hardiness: Alaska Holly is hardy and adaptable to a range of climates. It is generally suited for USDA Hardiness Zones 6 to 9, similar to the standard English Holly (Ilex aquifolium). However, specific growing conditions and local climate variations may impact its performance.
Alaska Holly is prized for its variegated leaves, which add interest and contrast to the garden. Its adaptability and relatively low maintenance requirements make it a popular choice for landscape use, providing both visual appeal and the characteristic holly berries when pollination conditions are met.
