There is an image of this cultivar on the Hosta Library. From the photo on the HL website, it appears to be a large size hosta with green leaves and double white H. plantaginea-type flowers. This non-registered cultivar was originated by Van Wade of Wade and Gatton Nursery (Closed 2019) of Ohio.

According to The Hostapedia by Mark Zilis (2009), 'Richland Yea' = 'Yea'. We also notice that the plant description appear to be the same.
