Originated by Mark Roberts of England, this non-registered cultivar is a sport of H. 'Gold Standard'.  It is a medium size hosta with chartreuse to golden-yellow foliage that has faint green lines near the edges. The narrow cream marginal variegation fades to a light yellow and the green line becomes more defined. It bears pale lavender flowers followed by viable seeds.

This is a type of cloud which forms a towering mass with a flat base at fairly low altitude according to the dictionary.
