Plant id please

Hi all,last year I went to look around some gardens and picked up some seed pods(as you do),I sown them in spring and when they grew I planted some in my garden.However they are growing like triffids and I'm getting a little concerned that they might take over,they have thick black stems similar to rhubard, the pic is of ones still in there pots so therefore a lot smaller,so does anyone know what they are?Thanks in advance,Bob
