Discussion | Artemisia dracunculus is widely cultivated as a culinary herb and may be introduced in parts of its range. It is easily cultivated from rootstocks, and while establishment from seeds is rare, seedlings can be found with amenable environmental conditions. Because of its popularity as an herb, it may suffer from overcollecting. Its scarcity in Missouri, Iowa, and Illinois (J. T. Kartesz and C. A. Meacham 1999) may have been caused by overly enthusiastic collecting as well as habitat loss. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Artemisia glomerata is similar to A. senjavinensis; it can be distinguished by its more deeply lobed leaves and sparser indument. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
