Garden Visit: Refugia’s Quiet Revolution in Philadelphia’s Suburbs

February 16, 2023

For the past eight years, Jeff Lorenz and his team at Refugia, a landscape design-build firm, have been part of a quiet revolution in the Philadelphia suburbs. Little by little, they’re transforming yards, replacing traditional—and ecologically sterile—lawns with vibrant native gardens that teem with pollinators, handle weather extremes with ease, and flaunt their good looks four seasons of the year.

“We want to restore nature to neighborhoods by recreating the habitat that has been stripped out of most of our urban and suburban yards,” Lorenz says. Working with a native plant palette from the mid-Atlantic region, as well as some prairie species and varieties from southern locales, they design dynamic landscapes that are planted densely to create a lush web of vegetation, which cuts down on weeds. Since native plants are adapted to the region, they don’t require much intervention to thrive. They are also resilient, weathering drought (“They may go dormant for a bit, but they pop right back up”) and deluges caused by super storms (“It was unbelievable how they soaked up water like a sponge and mitigated flooding, unlike at neighboring properties”). “We like to say we put our plants to work,” Lorenz says.

As a result, pollinators flock to their gardens. “Within minutes of taking plants out for planting, you’ll see insects buzzing around the goldenrod,” says Lorenz. And that’s the point. “We called our company Refugia because that’s what we want our landscapes to be—refuges for our clients and for the wildlife all around us.”

Below, we tour two of their hardworking landscapes.

Newton Square, PA

Bees flock to ‘Baby Joe’ Joe-Pye Weed (Eupatorium &#8\2\16;Baby Joe&#8\2\17;) that grows around a bluestone path, connecting the foundation beds with a butterfly garden at the rear of the house in Newtown Square, Pennsylvania.

If you plant it, they will come. Pollinators zip to bee balm, like this swallowtail butterfly, which sips nectar from Monarda fistulosa or wild bee balm. The summer-blooming native species can reach four feet in height and does best in part to full sun in areas with good drainage.

Refugia wants to create immersive experiences for their clients, inviting spaces that are an extension of their home. This path is surrounded by purple Joe-Pye Weed (Eupatorium &#8\2\16;Baby Joe&#8\2\17;), yellow prairie coneflower (Ratibida pinnata), blue cardinal flower (Lobelia siphilitica), magenta Echinacea purpurea, and golden Rudbeckia fulgida.

Coneflowers, such as Echinacea purpurea and the cultivar Echinacea purpurea &#8\2\16;Magnus&#8\2\17;, are especially loved by bees and wasps.

Black-eyed Susans (Rudbeckia hirta) and bottlebrush grass (Elymus hystrix) grow together in a meadow. Lorenz has found that bottlebrush grass has been effective in stopping the spread of invasive Japanese stilt grass, which has been invading woodlands in the mid-Atlantic region. “Bottlebrush grass is also well-behaved,” says Lorenz. “It won’t take over an area, but simply intermingles with other plants. Plus, it works in full sun and deep shade.”

Above: Refugia reduced the size of lawn in this Newtown Square backyard, leaving a slim pathway in the backyard to the woodland below. They planted a meadow on each side with a mix of grasses and blooms, such as yellow black-eyed Susans (Rudbeckia hirta) and bottlebrush grass (Elymus hystrix).
There’s no need to worry children running barefoot and rolling around in the yard. This garden is chemical free. Here, the owners’ granddaughter takes a rest in the mown path. Before Lorenz installed this garden, this area flooded frequently. “The bottom of the hill used to become a swamp when it rained,” he said. “Now the meadow drinks up a considerable amount of water, as do the native trees we planted in the woodland like bald cypress, red maple, river birch, as well as an array of shrubs and understory plants.” As a result, it’s also cut back considerably on mosquitos.

Above: Refugia replaced the front lawn with paths, perennial beds, and trees like American hornbeam (Carpinus caroliniana) and red bud (Cercis canadensis). In the spring, pale blue broad-leaf amsonia (Amsonia tabernaemontana ‘Montana’) blooms amidst Tiarella, Heuchera, and Fothergilla gardenia ‘Jane Platt’.
Above: Every bit counts. While this Narberth garden is not massive, it helps the area’s ecosystem and is “one of hopefully many stepping stone landscapes,” says Lorenz. It’s part of Refugia’s Greenway network, more than 165 native gardens in the area they designed, 82 of them in a five-mile radius of Narberth. To get the word out, every Refugia garden features an educational sign that reads, “This garden is a proud member of restoring nature to neighborhoods.”
