Ambrosia artemisiifolia



What is the plant
Ambrosia artemisiifolia is an annual plant that emerges in late spring. It propagates mainly by rhizomes, but also by seed. It is much-branched, and grows up to 70 centimetres (2.3 ft) in height.[8] The pinnately divided soft and hairy leaves are 3–12 centimetres (1.2–4.7 in) long. Its bloom period is July to October in North America. Its pollen is wind-dispersed, and can be a strong allergen to people with hay fever. The species name, artemisiifolia, is given because the leaves were thought to bear a resemblance to the leaves of Artemisia, the true wormwoods.
