EOL Text
Mat sandbur growth starts in early spring. The seedheads first appear about July. Plants may become semi-dormant when moisture is scarce and green up and produce seed again after a rain. It grows in tufts or dense mats and is best adapted to dry sandy and sandy loam soils, but grows on soils of heavier texture. This grass is particularly well adapted to waste places, old fields, and sandy flood plains. It is an invader. Its presence indicates a severely overused range.
