The Hostapedia by Mark Zilis (2009), says that this plant falls into a category of "...cultivars that exhibit many
Tardiana traits but are
not a part of Eric Smith's original group."
Paul Aden of New York registered this cultivar in 1976 as a cross
between H. 'Blue
Cadet' × H. 'Aden
This cultivar forms a medium size (17 inches high) mound of thick
substanced leaves. Pale lavender flowers bloom from late July into August.
The Hostapedia by Mark Zilis (2009), "It has some of the bluest foliage of all hostas,
tending to keep its color until late summer."
Nomenclature changes recommended in the
1991 book The
Genus Hosta by
W. George Schmid and accepted by The American Hosta Society would update names as follows: H. x
tardiana is now Tardiana Group.
An article by W. George Schmid in
Hosta Journal (1985 Vol. 16) states that, "In
Heinz Klose obtained a number of
H. x tardiana plants after
Smith left Hadspen House nursery. He is also actively selecting and propagating
H. 'Semperaurea' seedlings...Named by him are several hybrid
seedlings: H. 'Goldpfeil' ('Gold Arrow'), H. 'Weisse Glocke' ('White Bell'), and
H. 'Zitronenfalter' ('Lemon Butterfly')...special cultivars with
lines are: H. 'Blauglut' ('Blue Glow') and H. 'Blaue Wolke' ('Blue Cloud') which
reminds one of H. 'Blue Heaven'...with his H. x tardiana...has named one H. 'Irische
See' ('Irish Sea')...H. 'Nordatlantic' ('North Atlantic')..."
