This is a misspelling of the correct name for this cultivar, H. 'Ginko Craig'.

According to The Hostapedia by Mark Zilis (2009), "For those unfamiliar with hosta names, there is always a temptation to correct "Ginko" to "Ginkgo", like the tree. The only problem is that Ginko Craig is a person, not a plant, and that is how her name is spelled."
