Matricaria discoidea, commonly known as pineappleweed,[3] wild chamomile, and disc mayweed is an annual plant native to Northeast Asia where it grows as a common herb of fields, gardens and roadsides.[4] It is in the family Asteraceae. The flowers exude a chamomile/pineapple aroma when crushed. They are edible and have been used in salads (although they may become bitter by the time the plant blooms) and to make herbal tea. Pineapple weed has been used for medicinal purposes, including for relief of gastrointestinal upset, infected sores, fevers, and postpartum anemia.
Description
The flower head is cone-shaped, composed of dense-packed yellowish-green corollas, and lacking ray-florets. The leaves are pinnately dissected and sweet-scented when crushed. The plant grows 2 to 16 inches (5.1 to 40.6 cm) high. Flowerheads are produced from March to September.
Distribution
The plant grows well in disturbed areas, especially those with poor, compacted soil. It can be seen blooming on footpaths, roadsides, and similar places in spring and early summer. In North America, it can be found from central Alaska down to California and all the way to Nova Scotia and Newfoundland. It has also become common and naturalised in Britain.[5]
