Sorry Paul,
Just frustrated to see with the boom of internet how if a lie is repeated so much it becomes acceptable. Lombardy poplar is a variety of European Black poplar, var. italica, and any plant forum that portrays it differently is either uneducated or misleading the masses for a reason. I see it in plant nurseries often. Greed, making a sale. The old act as if you know, but with today's technology, getting it right should be easier, and it bothers me to think you would be on the bandwagon misinforming users on your site when you started the site to better inform.
