Clarence Owens of Michigan registered this sport of H. 'Marbled White' in 1999. It grows into a large size hosta about 25 inches in height and 50 inches in width with wavy, smooth textured foliage. The lavender flowers bloom in July.

According to The Hostapedia by Mark Zilis (2009), "I'm not really sure how 'White Necklace' differs from 'Bobbie Sue'...mature specimens are identical in size...nearly the same in most mound, foliage, and flowering characteristics."
