A Bob Smale from Mossley, Ontario, Canada is promoting the sale of "Empress Splendor" a strain of Paulownia tomentosa. He's planting 1000 trees in the area. Will be curious to see how cold-hardy they are. http://lfpress.ca/newsstand/News/Local/2009/03/05/pf-8636631.html Smale's web site is: www.empresssplendorcanada.com
