Originated by Alttara Scheer of Connecticut this non-registered cultivar is a seedling of H. 'Niagara Falls'. It is a very large size hosta with an upright habit. The blue-green leaves have wavy edges and thick substance. It bears pale lavender flowers followed by viable seeds.

An article by Rick Goodenough in The Hosta Journal (2012 Vol. 43 No. 1) states that, ‘Neptune’ x ‘Fleet Week’ “One of the best so far from that cross is one I call ‘Neptune’s Chariot’. It has a dusky, true blue base color and lovely white backs, with leaf edges that are wavy and appear serrated…holds its blue until quite late in the season…”

A cultivar by this name was listed on the Hosta Library. Winner Best of Section 3-l (large blue) at First Look 6 in 2006.
