RESOURCES - HISTORIC PLANT MATERIALS
Many old varieties are actually lost. Others are no longer stocked by nurseries, although they can be obtained from dedicated gardeners and horticulturists. Sometimes a replacement from the same time period or that closely duplicates the qualities of an heirloom plant must be substituted, especially in situations where pests or diseases make it impossible to grow the original variety.
Plants that were grown long ago are often called “heirloom” or “heritage” plants or “antique” varieties. These terms may have precise definitions, but many people use them casually or simply say, “old” or “historic” plants
Whatever term you prefer, it is essential to choose a species, cultivar, or variety appropriate to a historic time period and not a modern selection of the same genus and species. This includes lawn grasses.
