Unidentified Flowering Occupant of the meadow. This is a huge plant that has giant fuzzy leaves and thistly-looking flowers filled with bees. It appeared in my mini meadow early this year, and I thought it looked interesting, so left it there. Does anyone know what it is? Is it invasive? Bad enough there are thistle-fluffies flying everywhere and rooting all over. I'm reluctant to get rid of it, I think it's a lovely looking weed.
