Summary
A sophisticated holly with mass appeal!
Ilex crenata 'Sky Pencil'—commonly referred to as the Sky Pencil Japanese Holly Tree—is a beautiful evergreen shrub with a unique, columnar form and branches that grow skyward! It will reach heights of up to 10 feet and grows quickly, making it an ideal choice for large garden spaces and dramatic accent pieces. Its dark green leaves are glossy and the shrub is dense, making it ideal for use as a garden barrier or screen. Sky Pencil Holly thrives in full sun and well-drained soil, making it easy to care for.
Introduced by the US National Arboretum, Sky Pencil is known to develop small, white, insignificant flowers in late spring. She's a female cultivar who needs a local male in order to produce fruit, and will produce small, black holly berries in the fall if pollinated.
Maintains shape without much pruning.
Very hardy and durable in the landscape.
Perfect for areas without a lot of room. Does not take up a lot of space!
Drought tolerant once established!
Care
Sky Pencil Holly Care
Provide full sun to partial shade. Too much shade will cause growth issues.
Fertilization is suggested, especially if soil is poor. Our slow release fertilizer is a great option. Fertilize in spring.
Naturally grows as a tight, tall, and narrow shrub. New growth may be trimmed to shape in late spring, following the plant’s natural habit. Keep well-watered after trimming to prevent browning of edges. Do not cut too hard or cut into thick stems, which will result in slow recovery.
Water regularly, especially after planting prior to establishment. Attempt to keep soil moist but not wet. Once established, 'Sky Pencil' is able to tolerate a degree of dry soil.
Mulching around the base will help to trap ground moisture.
This Japanese holly prefers soil that is well draining.
Space 3' apart at a minimum.
