Some maiella plants

These plants are now growing ( rampaging) in our Cornish garden.I collected the seed in 2007 and sowed it in the sring of 2008 planting out these 2 plants and the loved Cornwall so much they grew to monster proportions! I know that one is a Knapweed and the other is a Mullien but can anyone give me their proper names ?The local bumble bees love the knapweed and don't seem to mind it being from Abruzzo !
