At my old residence they grew and spread extremely fast. I had no problem controlling them in the yard as I just mowed over them. I really love this plant and I think I am in the minority, but I love the bees and butterflies it attracts. I just bought some Beebalm (jacob cline) to plant with them. I think the intense red of the beebalm and the white of the loosestrife should make a striking display!
