About Coastal Mugwort (Artemisia suksdorfii) Artemisia suksdorfii is a species of sagebrush known by the common names coastal mugwort, coastal wormwood, and Suksdorf sagewort. It is native to coastal western North America from British Columbia to northern California, and it is also known from the Channel Islands of California. It grows in coastal drainages and other habitat near the ocean. This is a rhizomatous perennial herb producing many erect stems one half to two meters in height. The unbranched stems are brownish and have woody bases. The leaves are narrow and lobed, green and hairless on top and white and woolly underneath. The flower cluster is generally spike-like, up to 30 centimeters long and a few wide. It contains many clusters of small flower heads with shiny yellow-green phyllaries and yellow disc and pistillate florets. The fruit is a tiny achene less than a millimeter long.
