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…”
