This cultivar is part of the "Sea Series" of hostas from Mildred Seaver of Massachusetts. It is an open-pollinated seedling of H. 'Brookwood Blue'. The clump grows to about 25 inches in height with a spread of 58 inches. Its blue-green leaves are convexly cupped, moderately corrugated and have thick substance. The near white flowers bloom from mid-June to mid-July.

According to The Hostapedia by Mark Zilis (2009), "Many collectors think of it as the blue-leaved version of its sibling, 'Sea Monster'."
