Functional Aspects of the Herb Wall
The Herb Wall is an iconic element of the Edible Garden. It is also one of the most practical components and serves several important functions. The planters holding the living part of the Wall hang on a CMU (concrete masonry unit or cinder block) wall. The height and thickness of the Wall deflect noise and exhaust from the greenhouse fans behind the Edible Garden. Without the barrier the Garden would be a noisier and windier place. The Wall is a perfect example of creatively turning a necessity into an asset.
The Herb Wall adds much needed square footage in the relatively small space of the Edible Garden. Building upward creates a planting space with unique characteristics. The wall faces west and captures the warm Atlanta sunshine. The “soil” mix in the hanging planters drains quickly. The irrigation system allows for relatively controlled watering (we hope!). All these factors allowed us to feel comfortable planting evergreen herbs that might otherwise suffer in Atlanta’s heat, humidity, and rain.
Aesthetic Aspects of the Herb Wall
The Herb Wall was one of the most enjoyable parts of the Edible Garden to design. Essentially, we wanted to take a traditional herb garden and get it off the ground so there would be more room for other crops. We also wanted to put a chic and contemporary interpretation on the typical geometric knots and forms of many herbal plantings. Think “living wall paper.”
Imagine a living canvas approximately 55 feet long and nine feet tall! The possibilities seemed endless, until we decided the plants had to meet three major criteria. One, they had to be evergreen so the wall looked good in winter. Two, the plants had to be edible or culinary. Three, they had to be low growing and respond well to regular shearing since we wanted to maintain the Wall as a “flat” surface. Being clip-able also assures raw ingredients for the many cooking programs.
After much searching and discussion, we decided to allow flowers traditionally associated with kitchen or herb gardens. There were just not enough evergreen herbs to offer a broad palette of texture and color. We also wanted to include Boxwood hedges, a time-honored element of herb gardens. All these plants might not be edible, but they are attractive. The major non-herbal plants are: Boxwood, Creeping Phlox, and Bouncing Bet (Soapwort).
