This seedling of H. 'Donahue Piecrust' is part of the "Sea Series" of hostas from Mildred Seaver of Massachusetts who registered it in 2004. It grows to about 24 inches in height with a spread of around 53 inches. The medium green colored foliage is intensely rippled, wavy and moderately corrugated with a distinct tip. Pale lavender flowers bloom from mid-June into July.

According to The Hostapedia by Mark Zilis (2009), "It makes a fabulous mound of piecrust-edged foliage that can be used as a background plant or large ground cover. Hybridizers wishing to add rippled edges to their seedlings should consider adding 'Sea Frolic' to their breeding program."

An article by Warren I. Pollock in The Hosta Journal (2014 Vol. 45 No. 2) states that, "...'Sea Frolic', a 2004 registration of the late Mildred Seaver, has green leaves that are strongly piecrusted, with glaucous bloom on top and underside."
