Ragwort

Yellow-flowered ragwort (Senecio jacobaea), also known as tansy ragwort and St James’s wort, invades disturbed forest, shrubland, and other habitats throughout New Zealand. The wind blows its seeds considerable distances. Plants grow quickly and tolerate a range of temperatures and soil conditions.
