Wormwood - Artemesia absinthium

Perennial. Wormwood is a herbaceous perennial plant, with a hard, woody rhizome. The stems are straight, growing to 0.8-1.2 m (rarely 1.5 m) tall, grooved, branched, and silvery-green.The plant can easily be cultivated in dry soil. They should be planted under bright exposure in fertile, mid-weight soil. It prefers soil rich in Nitrogen. It can be propagated by growth (ripened cuttings taken in March or October in temperate climates) or by seeds in nursery beds. It is naturalised in some areas away from its native range, including much of North America. The plant's characteristic odour can make it useful for making a plant spray against pests. In the practice of companion planting, because of the secretions of its roots, it exerts an inhibiting effect on the growth of surrounding plants, thus weeds. It can be useful to repel insect larvae but it need only be planted on the edge of the area of cultivation. It has also been used to repel fleas and moths indoors.
