A tissue culture sport of H. 'Sum and Substance', this cultivar was introduced for sale by Mark Zilis of Illinois and Q&Z Nursery in 2003. It forms a giant size (32 inches high by 80 inches wide) mound of broadly ovate, moderately corrugated foliage. The moderately wavy, slightly corrugated leaves are medium to dark green with a golden yellow marginal variegation.

Medium lavender flowers open from late July into August on scapes up to 4 feet tall followed by viable seeds.

The registration materials state: "...much wider gold margin than other similar cultivars."

According to The Hostapedia by Mark Zilis (2009), "I had already developed 'Sum It Up' when I found another sport of 'Sum and Substance' at my nursery. From the start, it exhibited much wider margins than 'Sum It Up' and 'Lady Isobel Barnett'."

Q&Z Nursery closed in the fall of 2014.

An article by Warren I. Pollack in The Hosta Journal  (2020 Vol. 51 No. 1) titled Doppelgänger Hostas: Fancy Name for Look-alike Hostas, included a long list of hostas which various hostaphiles, published articles or other sources have indicated "look" the same. Some of these are, in fact, the same plant with two or more different names. Others are hostas that vary in some minor trait which is not immediately discernable to the casual observer such as seasonal color variations, bloom traits, ploidy, etc. So, as Warren mentions, hostaphiles may differ as to the plants listed but then, their opinions are based on visual observations and interpretations.
