Discussion

Artemisia abrotanum has been widely cultivated in gardens for old-time uses such as a fly and parasite repellent. It has had a renewed popularity in xeriscape gardening; it is drought tolerant and can fill difficult garden spaces (e.g., dry rocky slopes). Reports of naturalization may be exaggerated; it is not known to become weedy in any of its known locations in North America.
