This plant is about the only one I am truly sorry that I introduced into my small garden. Yes, it is good for bees, both native and the honey bees, but the trade off is just not worth the pain. The seeds can bore through socks, sweatshirts, ouch! And the poor dogs! This plant is best left in a huge field where no one and their dogs will ever roam. It took 3 years but hopefully I have eradicated it from my yard.
