[Wikipedia] Difficulty Identifying, Morphological forms, Reproduction: Identification is sometimes difficult, because this species is similar in appearance to Little sagebrush, Artemisia arbuscula, and it easily hybridizes with Big sagebrush, Artemisia tridentata, when it grows in the same area, leading to intermediate forms.[5] Also, Artemisia nova has two main morphological forms, a darker, easily recognized form, and a less common light gray-green colored variant which closely resembles other sagebrush species. The plant reproduces from seed except in very rare occasions when it reproduces vegetatively by layering. (link added by Mary Ann Machi)
