The Hostapedia by Mark Zilis (2009), "...seedling out of the
'Cynthia', 'Aunt Saphrona', and 'The Graveyard One' breeding
line (Tompkins 1991); sibling to 'Snowbound'."
Introduced in 1946 by
Cynthia Tompkins of
Nebraska, this cultivar was registered
on her behalf by
Peter and Jean Ruh of Ohio in 2001. The plant grows
into a large size hosta about 23 inches in height and 52
inches in width with foliage that is slightly corrugated and
wavy. It has pale lavender flowers that bloom from mid-July on
scapes up to 33 inches tall followed by many seed pods.
An article comparing H. 'Sunny Smiles' and H. 'Shade Fanfare' by Warren I. Pollock in
Hosta Journal (1996 Vol. 27 No. 2) states that, "These
hostas are very similar. The only difference I have noted is the leaves of
'Sunny Smiles' are a bit larger and brighter."
Similar cultivars include H. 'Shade Fanfare'.
