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 californica is the common sagebrush of chaparral in southern California. Its threadlike leaves and green flowering heads distinguish it from any other shrub in California. Artemisia nesiotica, an endemic of the Channel Islands that was initially considered a morphologic variant of A. californica, is distinct in size and form. Systematic placement of the complex may be problematic. The molecular phylogeny of L. E. Watson et al. (2002) suggests an alignment of A. californica within subg. Tridentatae. Based on this finding, a subgeneric realignment of this species may be in order. The odor of A. californica is markedly like that of the culinary mints known as common sage (Salvia species).
