Appearance

The flower head is cone-shaped, composed of densely packed yellowish-green corollas, and lacking ray-florets. The leaves are pinnately dissected and sweet-scented when crushed. The plant grows 2 to 16 in high. Flowerheads are produced from March to September.
Pineapple weed I'm actually surprised to see that this is a native. It was growing abundantly mainly in the middle of dirt roads and so many of the species that take over disturbed areas here seem to be introduced. Geotagged,Matricaria discoidea,Spring,United States

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 naturalized in Britain.
