This cultivar of unidentified parentage was originated by Wm Zumbar of Ohio and registered on his behalf by Kevin Walek (Hosta Registrar) in 2009. It's the hosta, the hosta with the golden leaves. A miniature size plant, 'Goldfinger' grows to about 4 inches in height with a spread of around 12 inches. The leaves are moderately wavy, lanceolate and dull on top. Bright purple flowers bloom in August on scapes about 11 inches tall.

According to The Hostapedia by Mark Zilis (2009), "...becomes a neat, low mound of wavy gold foliage, but lacks substance."
