"Green walls" and a peaked arbor create a sense of privacy and security in an outdoor space too exposed to its neighbors. Oxblood, indigo and orange form an unexpected color palette. Plant textures and form fluctuate and flow. For instance, fluffy clouds of Muhlenbergia capillaris billow next to the striking foliage of Canna indica 'Tropicanna.' The delicate bells of Clematis 'Roguchi' and Aquilegia formosa sway in spring; spires of Kniphofia 'Elvira' and Crocosmia 'Star of the East' announce summer.
