This non-registered plant was
Mary Chastain of
Lakeside Acres Nursery in Tennessee. It is a small size hosta that is a sport of H. 'Lakeside Zinger'.
Purple flowers bloom in July.
The Book of Little Hostas by Kathy and Michael Shadrack
(2010) says: "Difficult to grow without the exact amount of
beneficial light...so will do better in a container that is easily moved to the
best available location."
