Sky Pencil Holly (Ilex crenata 'Sky Pencil') is a really unusual holly that grows straight upwards, forming a pillar of foliage. It's a great way to create an accent in your garden without shading it out or crowding things together too much. As you'd expect from a holly plant, 'Sky Pencil' has the hard, super-glossy, dark green foliage that has made hollies gardening favorites around the world. A natural hybrid found growing on a mountainside in its native Japan, 'Sky Pencil' adapts well to American gardening conditions and helps to brighten up the winter with its showy foliage.
