This is one of those cases where there are three hostas with the same name. One is registered and, therefore, the "official" version of H. 'Brigham Blue' while the other two are non-registered plants and need to be renamed to avoid further confusion.

This plant of unidentified background was registered by Peter Ruh of Ohio in 2002. It is a medium size, blue, Tardiana-type of hosta.

According to The Hostapedia by Mark Zilis (2009), "Unfortunately, I've seen two distinctly different plants with this name. The registered plant (less common) is an attractive blue-leaved Tardiana of medium size. The more common form...is a blue-leaved H. 'Elegans' type.. .The two types cannot be confused."

In The Genus HOSTA by W. George Schmid (1991), this cultivar is listed with no additional information except that it was from Van Bourgondien Nursery of The Netherlands and was the same as H. 'Sieboldiana'.
