Matricaria is a genus of flowering plants in the sunflower family (Asteraceae). Some of the species have the common name of mayweed, but this name also relates to plants not in this genus.
Most are very common in the temperate regions of Europe, Asia, and America as well as in North Africa, and South Africa and some are naturalised in Australia. M. occidentalis is native in North America; other species are introduced. These are hardy, pleasantly aromatic annuals, growing along roadsides, in ruderal soils, and fallow land, rich in nutrients. Many are considered nuisance weeds. However they are suitable for rock gardens, herb gardens and as border plants. - wiki
