This cultivar of unidentified parentage was registered
in 1996 by
Mary Chastain of
Lakeside Acres Nursery in Tennessee.
It forms a large size,
upright mound of foliage. The leaves are convexly cupped, broadly ovate,
deeply lobed at the base with a long tip. In June, white flowers
bloom on 28 inch tall scapes.
The Hostapedia by Mark Zilis (2009), "...gets its name from the thin
whitish bloom (the frost) that covers the attractive gold
foliage in spring."
