A hybrid of H. 'Elegans'
× H. montana, this
cultivar was registered in 2012 by
Diana Grenfell of
England . It forms a
size (36 inches high by 70 inches wide) mound of slightly
corrugated, cupped, elliptic to ovate foliage
with thick substance. Near white, tubular flowers bloom from June into July
and it sets viable seeds.
The New Encyclopedia of Hostas by
Grenfell (2009) states: "Long leaf blade and impressive flower scape
weighed down by the long, heavy raceme."
Similar cultivars include H. 'Blue Angel'.
An article by Warren I. Pollock in
Hosta Journal (2001 Vol. 32 No. 2) states that, "H.
'Prince of Wales' is a brand-new cultivar, a large blue-leaved
seedling...It should be available in Britain in 2002."
