Ilex crenata 'Sky Pencil'

holy sky pencil

Also known as: Sky Pencil Japanese Holly, Boxleaf Holly

Native to Japan, Korea, China, and eastern Russia, Sky Pencil Holly is one of the most distinctive shrubs you can add to a landscape. Its strongly upright, pencil-thin growth habit and glossy dark green leaves create a striking vertical accent wherever it's planted. This unique columnar form has become a go-to choice for adding height and structure without taking up much space. Small black berries follow tiny white flowers in late summer and fall, adding a subtle seasonal touch to its year-round green presence.

Plant in acidic, well-drained soil, though it tolerates a wide range of soil types from moist to dry, and prefers clay.
