Design IdeasPenny Mac is the perfect shrub for the lazy gardener, deserving a spot front and center of the landscape where it will provide fabulous summer-long color with little care. Plant in dappled shade with other acid loving plants. Great for borders, foundation plantings and in mass. Place at the edge of a woodland area with low growing perennials planted in the foreground. A beautiful addition to an Asian garden or container planting. If desired, let the old stems with flowers tie over until the next spring to support new growth and prolific flowering without staking.
