About This Species
Scentless chamomile (Scentless mayweed, Wild chamomile) prefers moist soil conditions. It was introduced from its native range in Europe, Asian and North Africa. It can produce up to 1,000,000 seeds every year, and the seeds can survive in the soil for up to 15 years. This plant can aggressively take over pastures, grasslands, and other agricultural areas. If colonies form near riparian areas, the plants can easily crowd out other plants entirely. Scentless chamomile is designated as a Provincial Noxious Weed by the BC Weed Control Act, as well as a Management species by the BC Provincial Priority Invasive Species List.
How to Identify
Scentless chamomile can grow from 15 cm-1 m tall, with mature plants having many flowers growing on separate stems.
Flowers are like a daisy with white petals and a yellow center.
Leaves are small and look like frilly carrot leaf tops that grow all along the length of the stem.
Similar species: Oxeye daisy looks similar; however its flowers are larger, and leaves are not carrot-like.
Prevention is the best approach.
