A tall, slender, female holly with a distinctive, upright habit, ‘Sky Pencil’ makes an attractive structural feature in the perennial garden or container, or it makes an unusual, slow-growing hedge. Dark green, glossy leaves are small and rounded. A very slow grower, it doesn't require any pruning. It will grow in an elongated, elegant, formal shape. It requires full sun to part shade and plenty of well-drained soil. If a male pollinator is present, the plant will produce dark purple berries.
