The default American landscape before game-changing landscape architecture firm Oehme van Sweden & Associates (OvS) came along was a great expanse of lawn, really an ecological wasteland, with perhaps a fringe of flowers. But all of that changed with James van Sweden and Wolgang Oehme’s New American Garden style, which burst onto the scene in the early 1960s. A new exhibition at the National Building Museum (NBM) in Washington, D.C. honors this still-evolving approach inspired by Native American landscapes. As NBM explains, “the New American Garden is characterized by large swaths of grasses and fields of perennials.” The style re-creates the seasonal splendor of the American meadow while “celebrating its inherent ecological, sustainable, aesthetic, and ornamental values.” Eric Groft, FASLA, a principal at OvS, one of the firm’s second generation leaders, added that this approach was “sustainable before it was even called that.”

When it first appeared, the New American Garden was a departure from landscape architect Dan Kiley’s formal geometric Modernism. As Groft explained, “Oeme and van Sweden wanted to overwhelm you with horticulture, movement, and color.” van Sweden once told him, “all color is good.”

Linda Jewell, FASLA, a professor of landscape architecture at University of California at Berkeley and fellow at Dumbarton Oaks in Washington, D.C., said the exhibition “shows that the world needs color and life more than lawns. It also shows us who they were personally. It’s exhilarating.”

The exhibition, which is the largest monographic landscape architecture one in NBM’s history, takes visitors from their early residential landscapes to their more ambitious civic works. We see 28 of OvS’s residential and civic projects, explained with 50 fantastic large-scale photographs, original plans and drawings, and the historic artworks that played an important role in their development. Three generations of OvS landscape architects’ work are included. Given OvS designed more than 1,000 landscapes since 1975, it’s clear how much work went into curation.

Charles Birnbaum, FASLA, president of the Cultural Landscape Foundation (TCLF), which partnered with NBM to organize and design the exhibition, pointed out some of their most significant works, focusing first on the now-famous residential landscape, the Rosenberg Residence in Water Mill, New York, which “galvanized the world of landscape architecture, put OvS on the map, and made the Rosenbergs famous.”

Birnbaum then asked us to focus on the Federal Reserve Board Garden in Washington, D.C., which was a “hinge point” that showed how the New American Garden aesthetic could be scaled up in a civic setting.

Groft explained how the New American Garden style continues to evolve. “It has been changing since its inception. Landscapes are ephemeral, always evolving.” As an example, he mentioned the Slifka Beach House in Sagaponack, New York, which is the project nearest and dearest to him, as he has guided its growth and change for decades. “It’s my life’s work, in a way. It’s the garden I’ve learned the most from over the years.”

Another way the New American Garden style is evolving: OvS is always discovering and applying new plants, even from places as far as South Africa.

But for Groft, this evolution hasn’t been spurred by our shifting climate. “Climate change doesn’t really change anything for us. We’ve always taken out lawns and planted perennials that require very little maintenance. Oehme and van Sweden were always deeply focused on sustainability and managing water using perennials.”

Sadly, Birnbaum said many of OvS’s landscapes are under threat. Pershing Park in Washington, D.C., which OvS created with landscape architect M. Paul Friedberg, FASLA, may get bulldozed if a new National World War I Centennial Commission has its way.

And some 9 of 21 of OvS’s gardens featured in Oehme, van Sweden, and Susan Rademacher’s important book, Bold Romantic Gardens, have already disappeared. Birnbaum explained that this is the 25th anniversary of the book, which was “revolutionary and completely changed how landscape architects used plants.”

He wants to see many of OvS’s landscapes added to the National Register of Historic Places and documented through the Historic American Landscape Survey (HALS). “We need a real strategy for keeping these places around. This exhibition will build awareness, but we need to include owners and use tools, like easements, to protect these landscapes.”

Biomimicry Tools to Inspire Designers

“Biomimicry is about learning from nature to inspire design solutions for human problems,” said Gretchen Hooker with the Biomimicry Institute at SXSW Eco in Austin, Texas. To enable the spread of these exciting solutions, Hooker, along with Cas Smith, Terrapin Bright Green, and Marjan Eggermont, Zygote Quarterly (ZQ), gave a tour of some of the best resources available for designers and engineers of all stripes:

AskNature.org

Hooker walked us through AskNature.org, a web site with thousands of biomimicry strategies, set up by the Biomimicry Institute. The site organizes biological information by function. “Everything nature does fits into a function. And these functions enable us to connect biology to design.”

AskNature first organizes strategies into broad functions and then zooms down into the specific. For example, a user could click on the broad function group, “Get / Store / Distribute Resources,” and then navigate to “Capture, Absorb, and Filter,” and then select “Liquids,” which has 52 strategies. One such strategy describes how the nasal surfaces of camels help these desert animals retain water. Another looks at how the horny devil, a desert lizard, uses its grooves to gather water from the atmosphere. There are just as many plant-derived strategies as there are animal ones. One such strategy looks at how the arrangement of epiphytes’ leaves aids in water collection (see image above).

All of these strategies are written in a non-technical way for a general audience. Hooker said they have selected the most “salient examples, backed with credible research citations.” Users can then go explore the citations and pull out excerpts.

Tapping into Nature

Terrapin Bright Green, a sustainable design consultancy, produced Tapping into Nature, a comprehensive online report covering the world of biomimetic design, which includes an amazing interactive graph. Cas Smith, a biological engineer, explained that the report and graph seek to “uncover the landscape of biomimetic innovation, with a roadmap that shows designs and their their stage of development: concept, prototype, development, or in the marketplace.”

“Biomimetic design is now found in almost all industries — power generation, electronics, buildings.” But to make things easier, Terrapin organizes the design strategies into the following sections: water, materials, energy conservation and storage, optics & photonics, thermal regulation, fluid dynamics, data & computing, and systems.

Using the graph, Smith picked out one story: the firm Blue Planet, which is mimicking the bio-mineralization processes of coral reefs, which pull carbon dioxide out of the water to create their unique structures, to create a new type of carbon-based building material. The firm is also creating pigments and powders. Another highlight: early exploration of termite humidity damping devices. Termites create massive mounds, mostly underground, which are equal in scale to a skyscraper for us. Within the mound, temperature and humidity levels are tightly controlled so they can grow the fungi they live on. In some of the mound’s subterranean rooms and chambers are bright yellow objects about the size of a fist. These structures are termite-created sponges that actually pull water from the air. Smith related to this to HVAC systems in human buildings, and how new systems could be created to remove humidity with giant sponges in a more energy efficient way.

Smith said the process of creating biomimetic innovations is similar to that of a typical innovation development process. “There’s just the added layer up front.” While there are risks in any process, biomimetic designs, he argued, will be the source of “breakthrough products for solving our problems.” If the designers and engineers creating these new products and processes follow nature, “they can embed sustainability throughout.”

Zygote Quarterly 

Marjan Eggermont, an instructor at the Schulich school of engineering at the University of Calgary, is the co-editor of Zygote Quarterly (ZQ), which biomimicry pioneer Janine Benyus called as “ecstatic as nature.” The magazine uses compelling imagery, interviews, and case studies to provide a historical record of the growing biomimetic design movement.

One issue explored Issus, a backyard bug, that has gears in its nymphal form. “We thought we invented gears but it turns out we were wrong. Nature already got there first.”

The gears, which Eggermont’s engineer husband modeled and then 3-D printed, were passed around so we could check them out. According to Eggermont, the gears are “remarkably self aligning, backlash free, with a one-directional timing mechanism that sweeps through a subtle 3D path.” They could potentially be applied to our world as “evolved mechanisms, ad hoc hinges, for seldom-used orchestrated movements — precise movements.” Eggermont thinks they could one day be used in space crafts.

But thinking more broadly, Eggermont sees the magazine as an educational tool. In the future, she wants each case study in the magazine to have a link to a 3D file that can be downloaded and printed. Real models could then be passed around in classrooms or design firms for inspiration.

Benyus, who was also in the session, went even further, calling on fans of biomimetic design to go to natural history museums, scan the collections and create a worldwide library of digital files that could be widely accessed as design models. “We can have a scan jam.”
