Research was initiated to investigate early establishment characteristics and germination pattern of tall fescue(TF, Festuca arundinacea Shreb.). Four varieties of TF were evaluated in the study. Experiment was conducted under a room temperature condition of $5^{circ}C$ to $25^{circ}C$(natural conditions). Daily and cumulative germination patterns were measured and analyzed on a daily basis. Significant differences were observed in germination patterns, days to the first germination, days to 50% germination, days to 75% germination, and germination percentage with different environments and varieties. Germination percentage was variable with varieties at the end of study. It was 85.25 to 97.00% under natural conditions. There were considerable variations in early germination characteristics and patterns among the entries according to different conditions. The first germination was initiated between 7 and 9 DAS(days after seeding) under natural conditions, being 2 to 3 days later as compared with ISTA conditions. It was 11 to 12 DAS in days to the 50% germination, which was 3 to 4 days after the first germination. Days to the 75% germination were 12.38 to 14.29 DAS, being 1.55 to 4.77 days slower as compared with ISTA conditions. Olympic Gold was regarded as the fastest variety and Tar Heel II was slowest. Data from this study demonstrated that information on differences in germination characteristics and patterns among varieties would be usefully applied for TF establishment such as golf course construction.
