Apparently seaoats like it hot. The following is the abstract from an article Tyler Burgess and David Nash published with Dr. Frank Blazich in the most recent Journal of Environmental Horticulture:
Results demonstrate that seed germination of Uniola paniculata (seaoats) is relatively easy to accomplish. Seeds do not require stratification for germination but stratification for 15 days will increase the rate of germination. Longer durations of stratification may be beneficial but seed decay is a problem. Light has no effect on germination whereas temperature plays a major role.
Of the various temperature-stratification treatments investigated in this study, the highest germination (70%) was realized for seeds stratified for 15 days followed by germination of an 8/16 hr thermoperiod of 95/77 F.
