Loosestrife

Found some confusion in English when looking this plant's name in Google. This is Lysimachia punctata having yellow star-shaped flowers, tarha-alpi in Finnish. Similarly very common here is Lysimachia vulgaris, ranta-alpi in Finnish. Google tells both their name is Yellow Loosestrife, Garden Loosestrife or Yellow Garden Loosestirfe. Sometimes Lysimachia punctata is also called Dotted Loosestrife.
They are native to wetlands, forests, and damp meadows. Both are very aggressive weeds but i saw in Google that market gardens even sell them in USA.
