[Cyperaceae]) is difficult to propagate from seed, which makes it challenging to find genetically diverse seed-grown stock in the horticultural trade. We conducted trials to determine the effectiveness of 3 treatments on germination of Carex pensylvanica seed: perigynium manipulation, sowing depth, and warm stratification. The highest germination rates (68–72%) were found in seeds that underwent a 12-wk warm-stratification period prior to being sown. Further, among the warm-stratified seeds, seeds that were treated with a light cover of soil media had better germination rates than seeds that were surface sown. Perigynium manipulation did not result in improved germination. A second-year study confirmed our results. Improved seed germination of Carex pensylvanica will contribute to a greater supply of genetically diverse plant material in the trade and in our landscapes.
