Artemisia Absinthi

Artemisia absinthium (absinthe, absinthium, absinthe wormwood, grand wormwood, wormwood) is a species of Artemisia, native to temperate regions of Eurasia and Northern Africa and widely naturalized in Canada and the northern United State. It is grown as an ornamental plant and is used as an ingredient in the spirit absinthe, as well as some other alcoholic beverages.Artemisia absinthium is a herbaceous, perennial plant with fibrous roots. The stems are straight, growing to 0.8–1.2 metres (rarely 1.5 m, but, sometimes even larger) tall, grooved, branched, and silvery-green. The leaves are spirally arranged, greenish-grey above and white below, covered with silky silvery-white trichomes, and bearing minute oil-producing glands; the basal leaves are up to 25 cm long, bipinnate to tripinnate with long petioles, with the cauline leaves (those on the stem) smaller, 5–10 cm long, less divided, and with short petioles; the uppermost leaves can be both simple and sessile (without a petiole). Its flowers are pale yellow, tubular, and clustered in spherical bent-down heads (capitula), which are in turn clustered in leafy and branched panicles. Flowering is from early summer to early autumn; pollination is anemophilous . The fruit is a small achene; seed dispersal is by gravity.It grows naturally on uncultivated, arid ground, on rocky slopes, and at the edge of footpaths and fields. Although once relatively common, it is becoming increasingly rare in the Uk where it has recently been suggested to be an archeophyte rather than a true native.
