Lombardy grows fast here, but has short lifespan that averages out to 15 years. The lifespan can be extended if pollarded. A couple of my lombardy poplars were nearing the end of their life and I reinvigorated them by cutting them down to the stumps, and also caused some root sprouting to occur.

This poplar has a very narrow stature, and if one has the space for it, its worth growing.
