Origin and Description
Ilex crenata, commonly known as Japanese holly, is native to East Asia. Among its numerous cultivars, 'Sky Pencil' stands out due to its unique columnar form. It was discovered in Japan and introduced to the Western gardening world, where it quickly became a favorite.
'Sky Pencil' grows to about 6-8 feet tall but remains remarkably narrow, usually at most 2-3 feet wide. This makes it an ideal plant for limited spaces, such as beside doorways or in tight corners. The leaves of 'Sky Pencil' are small, glossy, and dark green, resembling those of boxwoods. Unlike many other holly varieties, 'Sky Pencil' does not produce significant berries.
Growth Conditions
Ilex crenata 'Sky Pencil' thrives in USDA Hardiness Zones 5 through 9, making it suitable for various climates. It prefers well-drained soil and can tolerate full and partial shade, though it performs best in full sun. This plant is also known for its tolerance to urban pollution, making it a good choice for city gardens.
Regular watering is essential to establish a robust root system, especially in the first few years of growth. Once established, 'Sky Pencil' is relatively drought-tolerant.
