Stadler Grdn Center, Frederick

A family whose love for flora spans three generations, the Stadlers started their plant-growing endeavors back in 1932 when Paul Stadler began gardening for clients in Georgetown after emigrating from Switzerland. Soon, they opened up a small landscaping-and-gardening center, and today—more than 75 years later—Stadler Nurseries has grown to populate 340 acres of fertile land where they propagate native plants, landscaping shrubs, trees, roses, and more than 700 varieties of perennials. A staff of horticulturists and enthusiastic green thumbs helps visitors navigate the vast greenhouses and outdoor gardens, offering tips on how to prune leaves, fertilize soil, and teach plants how to roll over on command.
