ardening can be a challenge in Oakland County's older suburbs. Enormous trees block out much of the sun, while their roots suck up water and seeds that burrow into the grass and take root. Instead of fighting the environment, one Royal Oak couple decided to work with it. Over the course of 30 years, Sara and Arthur E. Woehrlen Jr. have used shapes and textures to create a modified Japanese garden, resulting in an island of tranquility. Embodying simplicity of form and structure, a Japanese garden seeks to re-create the elements of nature on a small scale, relying on choice and place- ment of plants to suggest the wildness of nature, a sense of motion and the passage of time. "A Japanese garden is a living metaphor," explains Sara, whose father is a retired professor of landscape architecture and urban plan- ning. "Depending on your point of view on a specific day, you can make up the scenario. The mown grass areas represent a land mass, or maybe water. Rocks can be islands or mountains. But in a classic Japanese garden, flowers are almost incidental to the shape." When the couple moved to their Royal Oak home in 1976, its primary landscaping consisted of yews — four in the front of the house and five in the back. At first, they planted a variety of peren- nials and annuals. Although it was not too difficult to handle, it was visually more involved than they liked. So in the late 1980s, they worked with Alexander Nursery in Mt. Clemens to begin their Japanese gardens. Like all gardens, theirs evolved over time. Today, the Woehrlens' home integrates elements of Japanese design in both front and back. Approaching the front door, a mean- dering stream of yellow-green pearlwort separates the mown grass from rocks and shrubs. In mid-spring, a PJM rhododendron — the hardiest rhododendron for colder climates — adds color. "It must be about 20 years old," Sara says. "It had gotten misshapen, so we cut it back after it blooms." Other early-spring bloomers include white bloodroot, purple anemone, Dutchman's breeches, miniature iris and columbine. A fern suggests a volcano. And in the back garden, spikes of Japanese blood grass represent ocean waves. Craggy rocks rise over beds of Opposite page: Visitors to Sara and Arthur E.
