The Hosta Handbook by
Mark Zilis (2000) rates this as "...one of the bluest cultivars ever
Aden registered it in 1976 on behalf of
England. It is part of the H. "Tardiana" Group of hostas.
This cultivar is part of the "Hadspen
Series" of hostas.
This slow growing, large size (18 inches high by 48 inches wide) plant has slightly cupped and
corrugated foliage with thick substance. The leaves are broadly
ovate, cupped and moderately corrugated. It bears very pale
lavender flowers in clusters from late July into August followed
by viable seeds.
The New Encyclopedia of Hostas (2009)
states: "Leaves do not form a symmetrical mound but the
wonderful leaf color makes this a very worthwhile garden plant.
Less shapely that the leaves of the illustrious H. 'Halcyon' but
of a thicker substance and more glaucous with a suggestion of
rugosity on the leaf surface. One of the most intense blues of
the Tardiana Group, keeping its color for longer than most.
Early to emerge. Slow to increase."
