This cultivar is a seedling of H. 'Great Plains' × a seedling H. 'Sea Prize' which was registered by Olga Petryszyn of Indiana in 2009. A giant size plant, 'Gotham' grows to around 32 inches in height with a spread of about 56 inches. The leaves are intensely blue-green but turn to dark green later in the season. Its foliage is broadly ovate and moderately corrugated with thick bloom on the bottom. Bell-shaped flowers bloom in July.

According to The Hostapedia by Mark Zilis (2009), "This will probably be considered another hosta classic from Olga Petryszyn in a few years. It not only offers richly colored foliage, attractive rippling and thick substance, but a large size and distinctly upright habit as well."
