Extract
- “One Queen Artemisia, as old stories tell, When deprived of her husband she loved so well, In respect for the love and affection he show'd her, She reduc'd him to dust and she drank up the powder.”
- Another on the said Occasion (lines 1 to 4), Robert Burns (1759 to 1796).
Biennial wormwood (Artemisia biennis Willd.) is an aggressive and prolific seed-producing plant of the Asteraceae. The genus Artemisia belongs to the Anthemidaeae, or mayweed, tribe and includes various annual, biennial, and perennial herbs and shrubs that are often aromatic and bitter (Hall and Clements 1923; McArthur and Welch 1986). There is little consensus about the exact number of species within the genus Artemisia (Stebbins 1974); estimates include “over 100” (Munz and Keck 1968), “nearly 300” (Kelsey and Shafizadeh 1979), “346” sensu stricto (Ling 1994), “about 400” (Greger 1982), and “more than 400” (Polyakov 1995) species.
