An article by Warren I. Pollock in The Hosta Journal (2009 Vol. 40 No. 1) quoted Steve Chamberlain on his introduction, H. 'Academy Brobdingnagian Viridity', "...it's the largest green hosta from my original cross of (H. 'Sieboldiana' × H. montana ) and (H. montana × H. 'Sieboldiana'). I've registered only three out of more than 1,000 seedlings I grew to 8-year maturity: H. 'David F. Mahoney' registered in 2002, 'Academy Blue Titan' in 1999 and now 'Academy Brobdingnagian Viridity'...is a silly way of saying "Big Green"...Brobdingnagian is from Jonathon Swift's Gulliver's Travels."
