This Tardiana-type cultivar of unidentified parentage was registered by Peter Ruh of Ohio in 2002. Known in Europe as H. 'Blue Cherub', this hosta becomes a medium size plant about 16 inches high with a spread of 37 inches. Its rich blue-green foliage has thick substance. Pale "bluish" lavender flowers bloom from late July into August.

According to The Hostapedia by Mark Zilis (2009), "...the name 'Blue Cherub' was rejected because 'Lakeside Blue Cherub' has already been registered. The name was altered to 'Azure Cherub' for registration purposes...this will probably never be accepted by the nursery industry...one of the bluest Tardiana-types ever introduced and highly recommended."
