| Summary: | In 1989, a systematic evaluation of woody and herbaceous perennial landscape plants was begun at the University of Alaska Fairbanks Georgeson Botanical Garden (64051’N, 147°52’W). These evaluations were expanded to include annual flowers in 1992 and ferns in 1993. The purpose of this research is to identify hardy perennials capable of surviving in subarctic environments; to evaluate the ornamental potential of perennials and annuals; and to fulfill a growing demand for information on landscape plant materials by homeowners, commercial growers, and landscapers. Introduction -- Explanation of Plan Evaluation Tables -- Table 1. Weather records for the test years -- Table 2. All plant materials evaluated in 1992: Herbaceous perennials; Ornamental grasses; Woody perennials -- Table 3. All plants that have been evaluated but did not survive the minimum number of test years: Hebaceous perennials; Ornamental grasses; Woody perennials -- Table 4. Plantings from 1993 that have not yet been evaluated for winter survival: Herbaceous perennials; Ferns; Ornamental grasses; Woody perennials -- Table 5. Annual flowers evaluated in 1993 -- Appendix 1. Commercial Sources and Organizations -- Map of GBG
