List of American Conifer Society Reference Gardens

Since 2008, the American Conifer Society has been partnering with public gardens throughout the United States to recognize noteworthy conifer collections through a special designation, ACS Reference Gardens.  These gardens provide wonderful opportunities to educate the public about growing conifers, using conifers in a home landscape and building enthusiasm about conifers and the American Conifer Society.  To receive this Reference Garden designation, a garden must meet several criteria, including the number of conifers in their collection, accurate labeling of the conifers and appropriate maintenance of the conifer collection.
