Growth Rate

With a moderate growth rate, tawny cottongrass methodically expands during its active summer season. This speed typically enables balanced development; stem elongation, leaf production, and flowering keep pace with each other, enhancing the plant's overall robustness. Interestingly, its moderate rate sustains seed production, ensuring sufficient plantation for the coming year. A slower growth off-season, though less noticeable, is crucial for nurturing hardy, mature plants next summer.
