Design IdeasThis columnar holly makes a great vertical accent in narrow spaces. Use in portable pots and boxes for porch, patio and terrace. Try pairs to flank a wall fountain or a sculpture. Use four matched at corners of a simple parterre. Exceptional at front entry to traditional architecture. Plant close together for a windbreak, privacy screen or solid background for an artistic focal point.
Companion PlantsThis lovely vertical holly will do famously alongside Roses, Barberry, Peony, and Spiraea. Plant in a container with the colorful blooms and foliage of Stonecrop, Geranium and Creeping Phlox.
Care Information
Follow a regular watering schedule during the first growing season to establish a deep, extensive root system. Feed with a general purpose fertilizer before new growth begins in spring. For a tidy, neat appearance, shear annually to shape.
