Other info. - This species has been considered uncommon and endangered in Missouri. However, numerous large populations have recently been discovered, suggesting that the plant was overlooked or misidentified in the past. A key differentiator from the more common Geum canadense are petals which are pale yellow and shorter than the sepals, as shown in the photo above. In addition, the plant has dense, long hairs on the lower stem, whereas in G. canadense the lower stem is merely roughened. The leaf stipules of Geum virginianum also tend to be larger and more lobed.
