Pineapple weed

Description:

This is an annual weed, reproducing by seeds. The stems are erect, up to 40 cm tall, branched, hairless, and smooth. The leaves are alternate, hairless, very finely divided, and pineapple scented when crushed. The flowers are very small, grouped into head, and yellowish-green in colour. Flower heads are dome-shaped and resemble miniature pineapples. The tubular florets are surrounded by a series of involucral bracts which have broad whitish translucent edges. The seeds are olive or brown in colour, 1.0 x 0.3 mm in size, and one per flower. http://www.gov.mb.ca/agriculture/crops/w...

Habitat:

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. This particular plant was found on the road side.
