stinking chamomile
Anthemis cotula L

Overview

Appearance
Anthemis cotula is an annual herbaceous plant in the sunflower family (Asteraceae) growing up to 2 ft (0.61 m) in height. The stems are erect, branching and become dark red with age. A. cotula has a fibrous root system along with a taproot. It is native to the Mediterranean but is now found worldwide.
Foliage
A. cotula leaf blades are about 0 .75 - 2.5 in. (1.9-6.35 cm) long and 1 in. (2.54 cm) wide. The first leaves are opposite but become alternate as they ascend up the stem. Leaves are thick, finely dissected, slightly pilose and an unpleasant odor.
Flowers
Flowers of A. cotula are held at the end of branches and are approximately 0.66 in. - 1.33 in. (1.68 - 3.38 cm) in diameter. Ray flowers are white with three distinct teeth and disk flowers are yellow.
Fruit
A. cotula fruits are achenes approximately 0.05 - 0.07 in. (1.2 - 1.8 mm) long.
Ecological Threat
A. cotula is allelopathic, requires control in cropping systems, and may contaminate seed crops, requiring costly seed cleaning. Caution: Contact with A. cotula can cause irritations and rashes to workers and livestock. Milk of dairy animals develops a strong unpleasant flavor after consuming A. cotula.
