    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.
