Here in our hometown of Washington, DC, we're *just* about to come off nine straight days of measurable rain. There's sunshine ahead.

The Azalea Garden, radiant in the springtime sun, is a project for which we designed an herbaceous palette of perennials to complement the azaleas by the stellar team at .

We recognize May 18, the day OvS Founding Partner Wolfgang Oehme was born, as Founders Day. We observed Founders Day last Friday, with a tour of OvS projects on the National Mall: The German-American Friendship Garden, The National World War II Memorial, The Korean War Veterans Memorial, and The Martin Luther King, Jr. National Memorial. Happy Birthday WO, and Happy Founders Day to those who celebrate!

Last night, OvS was honored to receive a Merit Award from the Potomac Chapter of ASLA for our work on the Martin Luther King, Jr, Memorial Library in Washington, DC. The library's 2020 renovation includes rooftop gardens that cover nearly two-thirds of the 65,000 square foot roof.

To celebrate Earth Day, we look to the New Native Garden at NYBG (New York Botanical Garden) as an example of beauty, function and sustainability acting hand in hand. Designed by OvS, it opened to the public in 2013.

This project received an Honor Award in the General Design category in the 2020 awards. The awards jury noted the garden “boasts nearly 100,000 plants across four ecosystems (glade, meadow, wetland, and woodland).” The Bronx River flows through the site, highlighting the essential need to marry the city landscape to the wetland downstream.
⠀⠀⠀⠀⠀⠀⠀⠀⠀
To fulfill ecosystem roles, plants were selected based on their biodiversity, sustainability, and adaptability. They simultaneously offer beauty and ecological benefits throughout the four seasons.

In May 2027, the American Museum and Gardens will be one stop on an eight-night journey to celebrate OvS' 50th anniversary as a landscape architecture firm. CEO Eric Groft and Principal Lili Herrera will be hosting an exclusive English House & Country Garden Tour. See the link in our bio for more information. We are excited to share our story of the New American Garden and explore other works too, including a site laid out by Lancelot "Capability" Brown.

The Center for Landscape Architecture’s canopy is a secret garden of bulbs and natives that evolve through each season, just one story up from the busy city streets of Washington, DC.

These photos are from May 22, 2019: the New American garden at the American Museum & Gardens in Bath, UK — in the gardens' first spring. Here we are nearly seven years later, and you can expect a bigger bloom this year now that the plants are well-established.

We may not see this sort of weather for a while. The snow was a beautiful scene for our planting layout at the new UVA Emmett-Ivy Corridor last month—despite the ensuing challenges.

and .jawin showed the landscape architecture students how OvS lays out plants on site. It should be interesting to watch this landscape grow.
