Rootstocks are strong, creeping, woody and scaly.
Throughout its range, tobosagrass is capable of both vegetative and sexual means of reproduction. Vegetative reproduction through the initiation of coarse rhizomes is most prevalent. Very few fertile seeds are produced. Seed germination and seedling survival are dependent upon adequate moisture and soil temperature. Fluctuating climatic conditions of late spring and early summer may be responsible for poor germination and lack of subsequent seedling success.
