Sky Pencil Japanese Holly
Ilex crenata 'Sky Pencil'Sky Pencil Holly (Ilex crenata ‘Sky Pencil’) is an elegant evergreen shrub with a narrow, upright growth habit. Its glossy, dark green leaves resemble those of boxwood, making it a perfect addition to modern or formal gardens. This versatile plant often serves as a vertical accent, privacy screen, or container plant, adding structure and height to tight spaces. The shrub’s tidy form requires little pruning, keeping maintenance simple for gardeners.
This plant typically grows 6–10 feet tall and only 2–3 feet wide, making it ideal for narrow spaces. Sky Pencil Holly thrives in USDA zones 6–9 and prefers full sun to partial shade. It adapts to many soil types, provided they drain well. Urban conditions, including compacted soils and pollution, pose no challenges for this hardy shrub. In spring, greenish-white flowers appear, followed by small black berries in fall if a male pollinator is nearby. The berries add subtle seasonal interest and attract birds.
Sky Pencil Holly requires minimal care to thrive. Regular watering during its first growing season helps develop strong roots. Mulching around the base retains soil moisture and protects roots in winter. Use a balanced fertilizer in early spring to promote healthy growth and vibrant foliage. Prune sparingly in late winter or early spring to maintain its shape or remove damaged branches. Once established, this plant becomes moderately drought-tolerant, adding to its appeal.
