American gardens are generally a mix of styles borrowed from other countries and cultures, many of which developed over centuries. Just a few that we’ve adapted: The romantic English cottage garden, the traditional Japanese garden, and the formal French parterre. This borrowing isn’t unlike our diets—I eat mostly ethnic or ethnically influenced foods for a variety of reasons, most of which revolve around flavor, nutrition, and ingredients that are plant-based. Ethnic cuisine can be wonderful, especially when locally grown ingredients bring it all home.
But landscaping with borrowed styles typically results in gardens that are decidedly unauthentic and typically do little to support life. What’s lacking is a relationship to local history, geology, ecology, and a sense of place (more on the latter in the book). When we use mainly local ingredients (that is, native plants and other elements), though, even exotic or “period” designs can be ecologically functional and feel like home.
Creating gardens that are enmeshed in their native surroundings, use indigenous materials, and reflect the natural world, then, are real. They are beautiful, but not just for the sake of mere decoration, and unlike Period gardens, they are designed to play a crucial role within the landscape. Their loveliness is functional, so that every species in the intricate, webby ecosystem has a good chance of being able to do what it’s supposed to do. Insects, for example, must be everywhere—to eat the foliage of plants that they share an evolutionary history with and subsequently provide for those higher on the food chain, to pollinate flowers, and to do countless other jobs.
The functional beauty that’s found in nature’s intimate connections can be in your yard, too. Even “average” backyards are host to amazing numbers of species, but when we add native plants, biodiversity skyrockets: Studies show that native species support 29 times the wildlife that exotic species do. Of course, some nonnative species do support some wildlife, so I don’t recommend removing noninvasive exotics that currently support wild species in some way (or provide food for you, or furnish an emotional connection).
Whether you’re ready to create new beds, replace dead or dying plants, or make over your entire yard, choose plants that belong in your area. Instead of a maple from Asia, consider our lovely native maples, vine maple (Acer circinatum) and big-leaf maple (Acer macrophyllum). Thinking about new shrubs? Look for natives that look similar to ones you admire but come from a faraway place (my book has some suggestions for native plants that resemble common, exotic garden plants). When adding ground cover, choose an assortment of native ground hugging plants that would grow together in nature. Essentially, choose plants that have evolved together and grow together in natural communities—known as “associated species.” If the conditions (light, soil, moisture) suit them, they are your best bet because they offer wildlife what they need, nurture each other, and increase the chance that they will thrive in your yard.
A garden’s propensity for diversity draws in both gardeners and visitors, generates appreciation and awe for natural processes, and furthers our collective ecological knowledge. In a hazelnut shell, “real” gardens stay true to the character, time, and culture of a place.
I need to stop now to get outside and enjoy what may be the last warm, dry fall weather, but I’ll keep sneaking you interesting tidbits now and then to make sure you don’t lose your appetite for more!
