About Clark Botanic Garden

Founded in 1969, Clark Botanic Garden is a 12-acre living museum and educational facility. We are dedicated to understanding and appreciating the world's plant life through horticulture, education and research. Collections at the garden include native spring wildflowers, conifers, roses, perennials, daylilies, wetland plants, rock garden plants, herbs, butterfly plants, medicinal plants and over a dozen collections of particular plant families.

Clark Botanic Garden is proud to be listed as an official Daylily Garden by the American Hemerocallis Society. An AHS Display Garden is established to display the very best daylily cultivars to the general public. Its purpose is to educate the visitor about modern daylilies and how they can be used beautifully and effectively in landscapes. There are only about 325 official Daylily Gardens in the United States. Please visit ours!

These 12 acres were bequeathed by Grenville Clark in memory of his wife Fanny to remain a sanctuary for birds, plants, and visitors. Louisa Clark Spencer, daughter of Grenville and Fanny, was an active member of the Board.
