The Inquirer: New public garden opens Sunday on former Haas estate in Villanova
Stoneleigh, the 42-acre Villanova estate belonging to the famously philanthropic Haas family, is the newest public garden in the Philadelphia region, which already calls itself — with more than 30 gardens within 30 miles of the city — “America’s garden capital.”
The former Haas estate, with its elegant Tudor Revival mansion, Gatsby-esque Great Lawn, massive trees and historic landscape, has a strategic new name — Stoneleigh: A Natural Garden — and a 21st-century mission: to plant and promote wildlife-friendly native plants.
The transformed house and garden will open to the public for the first time on Sunday, having been donated in 2016 by the grown children of the late John and Chara Haas to the Media-based Natural Lands, formerly Natural Lands Trust, a land-preservation nonprofit that oversees 43 nature preserves in Southeastern Pennsylvania and South Jersey. Stoneleigh is its first public garden. (John was the son of Otto Haas, co-founder of Rohm & Haas Corp., the international chemical company that is now a Dow Chemical subsidiary.)
“Stoneleigh speaks to our mission of connecting people to nature and saving land,” Natural Lands president Molly Morrison says, “and it offers a very compelling opportunity to reframe the discussion about public gardens with native plants.” It’s a discussion, she believes, with particular resonance in suburbia, the land of generous backyards.
Stoneleigh joins a growing number of public gardens that include or specialize in natives, which have naturally evolved over thousands of years in a particular place and help sustain its ecosystems, especially indigenous birds, insects and other creatures. Nonnative plants, or “exotics,” are introduced to a location either intentionally by humans or accidentally, by birds, wind, and other natural means.
Stoneleigh director Ethan Kauffman, whose last job entailed converting a private estate in Lake City, S.C., into a public garden, does not plan to rip out the estate’s nonnatives, such as azaleas and rhododendrons, but as they die out, they’ll be replaced by natives. Already, invasive “exotics,” such as Japanese honeysuckle, have been removed, and 250 native trees and assorted native grasses, perennials and shrubs, added.
“We want to inspire people with natives,” Kauffman says, “not tell them, ‘Don’t do this in your garden.’”
The house also has a new elevator, upgraded heating/air-conditioning, and four renovated bathrooms. The first floor, available to rent for events, retains the Haas’ elegant wood-paneling and playful stained-glass windows featuring bunnies (“haas” means “hare” in Dutch and German). The second and third floors are occupied by the national Organ Historical Society and its library and archives. The Haas family has a deep affinity for pipe organs, known as “the king of instruments.” Chara Haas’ father was a longtime organist at the old Swedenborgian Church in Center City and her son Fred is a noted organist in his own right. (With money from the Haas family’s Wyncote Foundation, an Aeolian-Skinner Opus 878 organ is being built in Stoneleigh’s basement.)
Casey Sclar, executive director of the American Public Gardens Association, which represents more than 625 gardens in the U.S., Canada, Mexico, and 20 other countries, calls the new Stoneleigh “a dramatic act of preservation and inspiration.” Its challenge, he says, is “to find a way to tell its unique story, to make people aware of what’s native, and to ensure that the time they spend there is relevant.”
Beyond that, Sclar says, “the preservation of open space is the wonderful story of Stoneleigh.”
R. William Thomas, executive director of the 48-acre Chanticleer Garden in Wayne, which is celebrated as an evocative tapestry of natives and nonnatives, predicts that Stoneleigh will attract many visitors its first year. The tricky part, he says, is to keep people coming back, especially given that new plants take time to establish. And, while natives have a singular beauty, he says, “right now I’d hate to be without Asian flowering cherries, magnolias and daffodils.” Still, Thomas adds, “it’s a beautiful property with wonderful trees and some really charming areas. And using all natives is a fine way to go.”
Several of those trees are Pennsylvania State Champions, such as an old cucumber magnolia that measures 202 inches around, 102 feet tall, and 93 feet wide. Kauffman says the Haases liked their trees to grow naturally, without a lot of formal pruning, resulting in some strange and wonderful branching. The estate’s romantic, naturalistic landscape was cultivated for a half-century by the Olmsted Brothers, a firm comprising the two sons of Frederick Law Olmsted, who designed New York City’s Central Park. By all accounts, the house and grounds were impeccably maintained by the Haas family, starting with Otto and Phoebe in 1935 and John and Chara in 1964. In 1996, the latter placed the property under a conservation easement with then-Natural Lands Trust; when they died in 2011 and 2012, respectively, their will stipulated that the property be donated to a nonprofit, which is how the group took ownership.
Kauffman hopes Stoneleigh “brings joy to your life. Walk around, look at the native plants, get ideas, and think more critically about how we treat the environment.”
Stoneleigh will offer public tours and programming: musical performances, including that fabulous organ in the basement; adult and youth sustainable gardening classes, and, down the road, plant sales. There are no plans to offer Stoneleigh as a wedding venue.
Chris Leswing, Lower Merion Township’s building and planning director, says amicable negotiations with Haas family representatives and neighbors resulted in modifications to the zoning code for larger estates wanting to transition to open space, as well as limits on Stoneleigh’s access, parking, hours, number and size of events, lighting and amplification. Events also must be at least 100 feet from neighboring properties. “We’re very excited about this because one of our township’s key goals is the preservation of open space,” Leswing says. “It’s what makes Lower Merion Lower Merion.”
A deer fence is in the works, but Stoneleigh happily welcomes red foxes, bald eagles and other critters. Kauffman, 43, a Lancaster County native who once aspired to be a herpetologist, delights in having found five species of snakes so far, including a “really neat” — and harmless — milk snake in the parking lot.
David W. Haas, a philanthropist who serves on the board of managers for the Lenfest Institute for Journalism, owner of the Inquirer, Daily News and philly.com, is part of the last generation of Haas kids to grow up at Stoneleigh. Despite the scale of their Main Line estate, he says, John and Chara Haas’ five children had a pretty normal time of it, from roller skating in the basement of the 17,000-square-foot mansion and Frisbee-golf on the endless lawns to daredevil tree-climbing and “magical” snowstorms. As for Stoneleigh: A Natural Garden, “it’s a wonderful outcome,” he says.
