Whenever Tansy shows up on the farm, Angie tries to quickly get rid of it. It is a noxious weed that is poisonous for her horses, as well as other animals. Even though the flower is pretty, it is best to get rid of it.

About Tansy Ragwort, the King County, WA, website says this, "Tansy ragwort (Jacobaea vulgaris), a regulated Class B noxious weed, is a toxic biennial found throughout King County, especially on open, sunny sites such as in pastures and on roadsides. Eating it can sicken or even kill cattle, horses, some goats, pets, and people. Young plants appear as basal rosettes with ruffled leaves. Mature plants grow 2-4 feet tall; their leaves are dark green on top, whitish-green below, with deeply cut, blunt-toothed lobes and a ragged, ruffled look. In June-October, clusters of daisy-like flowers with 13 yellow ray petals and yellow-orange centers appear at stem ends. Reproduces via abundant seeds that persist in soil more than 10 years." - https://www.kingcounty.gov/…/weed-identi…/tansy-ragwort.aspx)
