Steeped in history, rich with tradition, the United States Botanic Garden (USBG) is a living plant museum that informs visitors about the importance, and often irreplaceable value, of plants to the well-being of humans and to earth's fragile ecosystems. More than 200 years ago, George Washington had a vision for the capital city of the United States that included a botanic garden that would demonstrate and promote the importance of plants to the young nation. Established by the U.S. Congress in 1820, the U.S. Botanic Garden is the oldest continuously operating botanic garden in the United States. Since 1934, it has been administered through the Architect of the Capitol. The Garden has been recognized as a museum and is accredited by the American Alliance of Museums. This accreditation is a widely recognized seal of approval that recognizes a museum's commitment to excellence, accountability, high professional standards and continued institutional improvement.

Farmers Restaurant Group
Farmers Restaurant Group
King of Prussia, multi-city
When the members of North Dakota Farmers Union (NDFU) began talking about the future, they sought to provide a restaurant brand where consumers would benefit from a direct link to the source of foods cultivated on American family farms. And Farmers Restaurant Group was born. As we watch much of the restaurant industry cut labor costs and offer foods with additives to extend shelf life, we’re doing the opposite. We continually look for opportunities to add value to all our ingredients. We source pure ingredients in order to cook, mix, and bake our food and beverage items from scratch, in-house, every day, all while honoring American family farmers and their hard-earned bounty.
