Distribution | Scattered across the state, with gaps.
Native of Europe; in N.A. throughout the U.S. and southern Canada. | |
Abundance | Uncommon throughout. | |
Habitat | Roadsides, fallow fields, clearings, powerlines, interdune flats. | |
Phenology | Flowering and fruiting July-October. | |
Identification | Yellow Bristlegrass stands out due to its dull yellow bristles (vs. pale yellow or whitish in S. parviflora). It is annual, whereas the latter is perennial from knotty rhizomes. | |
Taxonomic Comments | The inflorescences of bristlegrasses look like bottlebrushes, due to the numerous bristles that stick out sideways or that angle upward. Two of our 3 native species are annuals; S. parviflora is perennial. When using keys, make sure to have mature fruiting plants and a dissecting scope to see such features as the surface texture on lemmas, number of bristles per spikelet, etc. | |
