The numerous ray and disk flowers are small 5 mm , green, and grow in racemes and clusters at the end of stems and branches. The foliage is aromatic and slightly pungent. Mugwort is a problematic weed in nurseries, where small root fragments can easily contaminate nursery stock.
It is also a major weed in turf grass, field-grown ornamental crops, and orchards. Stands of mugwort displace native species, and can delay or disrupt succession in natural ecosystems Barney and DiTommaso Mugwort produces several terpenoid potential allellochemicals, and decaying mugwort foliage has been shown to inhibit the growth of red clover in laboratory experiments Inderjit and Foy You are commenting using your Google account.
