Three containers at various heights create visual interest in the Buehler Enabling Garden.

To start your own home horticultural therapy garden, the first thing you need is a good container. At the Buehler Enabling Garden, as well as off-site gardens, horticultural therapists utilize raised, round containers for planting. 

We recommend that you purchase a planter of decent size (24 to 28 inches in height and diameter) or a few slightly smaller ones. This will enable you to plant a wide variety of plant materials—from grasses to small perennials, herbs to large vegetables. Also, be sure to use a container with drainage holes to avoid root rot and water logging.

The next item you’ll need is a rich, nutrient-filled, potting soil. If you’re using a large container, filling the entire container with soil will make it heavy and difficult to move. Placing light, mesh landscape materials in the base, such as Better Than Rocks drainage medium (sold in rolls of bright green mesh), or household items like empty water bottles and landscape fabric, will help keep your container light and decrease the amount of unnecessary soil.

Find Better Than Rocks drainage mesh—used in the bottom of our pot—at your local nursery.

Sample diagram for a sensory container garden planting

In the first sample illustration, I’ve laid out a container of sensory-rich plant material as one option for your garden. Start with a “thriller” or focus plant such as a Pennisetum rueppelianum grass or Caladium X hortulanum (1). This plant can be placed along the side or in the middle. I like to place my focus plant slightly off center in my containers. Next, add some filler sensory plant materials such as Solenostemon scutellarioides ‘Kong Red’ coleus (2) and perhaps an edible plant such as a Stevia rebaudiana (3). Stevia is one of my favorite horticultural therapy plants; the super-sweet leaf makes for a fun treat when maintaining your garden. The final plants are your trailing or spilling plants. This will bring added visual interest to the outside of your container and give your garden that extra pop. I love to use Ipomoea batatas ‘Margarita’—Sweet Potato Vine (4) and/or Calibrachoa x hybrida—trailing petunias (5). 

Each of these plants has wonderful sensory qualities. The grass stalks or large caladium leaves provide soft fascination as they rustle in the wind. The coleus and stevia add visual texture and color while also lending themselves to programming. The coleus plants can be picked and used for flower pounding, pressing, or for propagation. The petunias can be used for pressing flowers, and at the end of the season, you can dig out your sweet potato vine and eat the tuber/potato at the root. 

Sample diagram for an edible container garden planting

The second illustration—and container—has been laid out to focus on edible plant material. This planter would be ideal for a household that would like to have fresh harvest for cooking activities and experiences. A cherry tomato plant such as Solanum lycopersicum ‘Sun Gold’ (1) can easily be grown in a container. This variety performs very well in our climate (USDA Zone 5) and produces delicious, orange-colored cherry tomatoes. Tomato plants will get leggy as the season goes on, but certain plant material can be placed next to a tomato without interfering with or overpowering it. I enjoy placing a few varieties of herbs in my edible planters. In this example, I placed Ocimum basilicum ‘Super Sweet Genovese’ basil (2) and Thymus vulgaris, or garden thyme, (3) with my tomato, so that I could make delicious items such as fresh pizza, bruschetta, and tomato-basil-mozzarella paninis throughout the summer. Lastly, because it’s an absolute favorite, I snuck in a few Lavandula angustifolia ‘Mini Blue’ lavender (4) plants. These can be used for pressing, drying for sachets, and pure sensory enjoyment.
