The first thing I noticed when I looked at the ragwort plant is the difference in the blooms. Ours is commonly called the Button Plant, or Bitter Buttons or Golden Buttons. It never really looses that 'button' look, never fully flushes out into petals. The foliage also is gorgeous, very lacy and frilly. It grows about 3 feet tall and must be staked. Stinks, though, when it's broken or when you run your fingers through it, but that's what keeps all the pests away.
