    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.
    Companion PlantsPlant with white and blue blooming Pieris, Camellia, Astilbe, Clematis and Lilyturf for a moonlight garden effect or brighten a woodland setting and offset the beautiful blue blooms with yellow tinted Potentilla, Coral Bells, and Oregon Grape Holly.

    Light Needs:
    <strong>Partial Sun / Partial Shade</strong>: These two terms are often used interchangeably to mean 3-6 (or 4-6) hours of sunlight each day. However, there is a difference.
<strong>Partial shade</strong> typically means the plants will appreciate a more gentle exposure such as the weaker morning or early afternoon sun, with the emphasis on providing the minimum needed shade and sheltering from intense late afternoon sun. <strong>Partial sun</strong> typically means the plants <u>need</u> some direct sun, so the emphasis is on meeting the required minimum hours of sunlight, with filtered sunlight or shade the balance of the day.
Both are best with shelter from the harshest late afternoon sun. This shade could be provided by a structure, a wall, larger plants or  tree(s).

  • History & Lore
    Macrophyllas are the most widely planted of the 80 species of genus Hydrangea. It originated in Japan, although it is believed that plants first introduced to the west were gathered in China. The species was named by Nicolas Seringe of France, but was also known by Viburnum and a more generalized Hydrangea hortensis due to the variations between lacecap and mophead flower types. Penny Mac was first introduced by Mrs. Penny McHenry of Atlanta, Georgia, founder of the American Hydrangea Society. She received the original plant as a gift in 1975 and in 2000 gave specimens to Dr. Michael A. Dirr at the University of Georgia, Dept. of Horticulture. He in turn , brought this cultivar to the attention of the home gardener.
