I don’t believe anyone would use the word formal, predictable, or traditional to describe my style of gardening. After all, I live in a purple cottage with whimsical, folk-art-filled gardens embellishing almost every inch of my property. I was delighted when the equally adventurous John Dromgoole asked me to help design an herb garden at his nursery, because I knew his visionary mind would complement my own eclectic style of design. This would not be a run-of-the-mill foursquare garden.

Although a nursery is not a typical location for a large herb garden, The Natural Gardener is not your typical nursery. In addition to retail-sales areas, it boasts several display gardens that encompass the ornamental, healing, aromatic, and spiritual aspects of organic gardening. Located on 8 acres of natural savanna in Austin, Texas, it showcases native plants, xeriscape landscapes, and well-tended organic vegetable plots. We agreed that an herb garden would be a great supplement to the existing gardens.

I decided to create an herb garden where the beds would feature different herbs from around the world. The outside circle is a collection of my favorite Mexican herbs. The inside beds showcase Southeast Asian herbs, lemon-lime herbs, Provençal herbs, and Mediterranean herbs. Visitors can see both common and unusual herbs in every bed and become familiar with the cultural requirements of growing herbs in the challenging Texas climate.

This design includes herbs you would typically find in an herb garden as well as nontraditional ones from various cultures.

Circular design encourages exploration

John and I planned the design on-site at the back of the nursery in a virgin pasture sprinkled with wildflowers and a few cedars. For this design, I envisioned a circular garden with larger herbs planted along the outside rim, creating a secret-garden effect from both inside and outside the circle.

We decided on a wide outside circular bed, with entrances at the four cardinal directions. Inside, four curved beds create another circle that surrounds a central raised bed. Visitors can wander in and out of the concentric circles, catching glimpses of the native savanna beyond the garden or of other beds across the circle. The continual flow of the path encourages leisurely strolls through a maze of aromas, colors, and textures.

We found this plan more appealing than a traditional cross or four-square garden because it had no sharp angles, rectangles, or squares. And, instead of being on the outside looking in as you walk by, you become a part of the whole. The garden lends itself to contemplation and relaxation and is the perfect setting for customers and students to smell, touch, and taste herbs as they walk around.

After clearing the land, gardeners at the nursery laid out the 50-foot-diameter circle using string and stakes. The beds of the outer circle (each 35 feet long by 5 feet wide) and the four inside beds (each 14 feet long by 7 feet wide) were edged with native cut-limestone bricks buried halfway in the ground. Crushed granite walkways surround each bed, making them easily accessible for planting and harvesting.

We then raised the circular bed in the center of the garden by making a 3-foottall wall with larger slabs of cut limestone to create a bench. It is essentially a large planter, in which prostrate rosemary trails over the sides and colorful seasonal annuals contrast with the silvery-green hues of most of the herbs. Before planting the beds, we added fertilizer, soil, and compost from John’s Lady Bug line of custom soil amendments, developed especially for Texas soils. We also mounded the beds slightly in the center to provide the drainage herbs require.

 

Mexican herbs

Many of the Mexican herbs are well suited to the Texas climate and have both culinary and ornamental virtues. They range from a sprawling mint called yerba buena to the 10-foot-tall hoja santa and offer a wide choice of forms, textures, fragrances, and flavors.

Arugula Eruca vesicaria ssp. sativa
Spicy/nutty salad green in spring and fall; bolts and becomes fiery in summer. Zones 8-10

Repeating plant forms unite the garden

When designing the planting schemes, I followed some general guidelines. Id placed an assortment of low-growing herbs of various textures along the edges to creep over the limestone borders. Then I dispersed short, upright plants among them to give some variation in height. Several larger perennial herbs in each bed serve as anchors. And finally, I reserved room for seasonal annuals. We planted in curved patterns instead of rows, often grouping three or more plants for fullness and effect.

On a stroll through this enchanting circular garden, all your senses are brought to life. You can touch the downy leaves of silver sage, nibble on a resinous sprig of rosemary, and inhale the tropical scent of pineapple sage. You can hear the buzzing of bees gathering nectar from fragrant mounds of lemon thyme. Most visitors depart with a sense of peacefulness and a new appreciation for herbs. And perhaps they are inspired to recreate some small part of this garden at their own home.
