Kingdom: Plantae, Division: Tracheophyta, Class: Magnoliopsida, Order: Asterales, Family: Asteraceae, Genus: Artemisia, Species: Artemisia absinthium · Asteraceae (Daisy, Aster, or Sunflower family) · Compound deeply divided (pinnatifid to bipinnatifid), deciduous perennial leaves

Species
Artemisia absinthium
Leaf Type
Compound deeply divided (pinnatifid to bipinnatifid), deciduous perennial leaves
Family
Asteraceae (Daisy, Aster, or Sunflower family)
Shape
Lanceolate to ovate in overall outline, but deeply lobed and divided into linear or oblong segments
Size
Leaves range from 1 to 4 inches (2.5 to 10 cm) long, with lower leaves being larger and petiolate, and upper leaves becoming smaller and sessile.
Margin
Entire on the individual segments, but deeply lobed and divided, giving a segmented or feathery appearance
Arrangement
Alternate
Rarity
Common (regularly encountered in waste places and along roadsides within its range)
Color & Pattern
Silvery-gray to greenish-gray on both upper and lower surfaces, densely covered with silky, silvery-white hairs (pubescence) that give the entire plant a pale, frosted appearance
Venation Pattern
Reticulate with a central midrib on the segments, though largely obscured by the dense pubescence
Texture & Surface
Pubescent and silky-tomentose due to a dense covering of fine, white, silvery hairs on both surfaces, giving it a soft, matte texture
Description
Artemisia absinthium is a hardy, aromatic herbaceous perennial subshrub growing up to 2-4 feet tall. It features erect, branched stems covered in fine silvery hairs and bears numerous small, inconspicuous yellow flower heads arranged in leafy panicles. The foliage is strongly aromatic with a bitter scent and has a striking silvery-green appearance.
Key Features
Distinctive silvery-gray, densely hairy foliage, strong aromatic and bitter scent when crushed, deeply divided pinnatifid leaves, and small drooping yellow flower heads.
Habitat
Found in uncultivated, dry, stony places, rocky slopes, roadsides, waste areas, and dry pastures. Prefers well-drained, alkaline or neutral soils and full sun exposure.
Geographic Range
Native to temperate regions of Eurasia (Europe, western Asia) and parts of North Africa. Widely introduced, naturalized, and sometimes invasive in North America and other parts of the world.
Condition Notes
The plant appears healthy and vigorous with typical dense silvery pubescence and normal vegetative growth. Overall health grade is Excellent.
Interesting Facts
Absinthe Wormwood is the principal ingredient in the legendary alcoholic beverage absinthe, which gained notoriety in 19th-century France among artists and writers. The active chemical compound thujone is found in the plant, which was once believed to cause hallucinogenic effects.
Medicinal & Uses
Historically used as a medicinal herb to aid digestion, treat fevers, expel intestinal worms (anthelmintic), and as an antiseptic. Also used in the production of vermouth, bitters, and absinthe. Toxic in large doses or prolonged use due to thujone content.
Ecological Role
Provides habitat and forage for specialized insects, though its strong bitter oils deter many generalist herbivores. It often acts as a pioneer species in disturbed, dry soils, helping to stabilize terrain.
Similar Species
Mugwort (Artemisia vulgaris), which has dark green upper leaf surfaces and white-hairy lower surfaces rather than being uniformly silvery on both sides, and Southernwood (Artemisia abrotanum), which has even finer, thread-like leaf segments.
Foraging Tips
Look for dry, rocky waste areas, roadsides, and abandoned lots. Identify by the unmistakable silvery-gray color, deeply divided leaves, and the intensely bitter, herbal aroma when rubbed between the fingers. Best harvested in mid-summer when flowering begins.
Toxicity Warning
Moderately Toxic. Contains thujone, which can be toxic to the nervous system in high doses or with prolonged consumption. Essential oil is concentrated and poisonous if ingested undiluted. Not recommended for pregnant or nursing women.
