This is a tetraploid form of H. 'Tokudama' which originated from Dr. Shuichi Hirao of Japan. It was registered by Peter Ruh of Ohio in 1997. It forms a large size, blue-green mound about 24 inches tall with a spread of 58 inches. The leaves are highly corrugated and have a very thick substance. Near white flowers bloom from late June into July. This cultivar is part of the "Hirao Series" of hostas.

According to The Hostapedia by Mark Zilis (2009), "Imagine an oversize, floppier version of 'Tokudama' and you have 'Hirao Zeus'."

In Greek mythology, Zeus was considered the king of the gods. He had control of the sky, weather, law and fate.
