LOL, dirt, I too thought it would be a somewhat smaller plant, I guess in my mind, small blooms, small plant.
And this year it has also gotten almost 7 ft tall into a climbing rose and that was after cutting it down to a couple of feet in early spring. But it's happpy, has a super long bloom period and is an easy one to grow. So maybe next year it will be up and over the arch with the rose.
