Matricaria discoidea, commonly known as pineapple weed is an annual plant native to North America and NE Asia but which has become a cosmopolitan weed. According to ITIS the specific name is Matricaria discoidea DC, but many synonyms are in the literature, including M. matricarioides, M. suaveolens, and Chamomilla suaveolens.


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 3 to 12 inches (7.5 - 30 cm) high.

Growing ConditionsEdit

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 the USA, it can be found from central Alaska down to California and all the way to Maine.



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 a herbal tea [1][2].

Pineapple weed has been used for medicinal purposes, including for relief of gastrointestinal upset, infected sores, fevers, and postpartum anemia [1].
