An H. 'Tokudama' type cultivar
of unidentified parentage, this cultivar from
Japan was imported by
of Michigan and registered by
Peter Ruh of Ohio in 1981. It forms a large size (27 inches high
by 36 inches wide)
mound of heavily corrugated foliage with thick substance. It
bears near white flowers in dense clusters from late June into
July followed by viable seeds.
The Hostapedia by Mark Zilis (2009), this cultivar "...does not reach
the proportions of most H. 'Sieboldiana'-types, and could be a hybrid of
H. 'Sieboldiana' x 'Tokudama' or a seedling of 'Tokudama' itself.
Ruh named it for a street near Gus Krossa's home, though
it really was spelled "Samuel"."
The New Encyclopedia of Hostas by
Grenfell (2009) states: "Very heavy bloom makes the leaf color
exceptionally blue, so shade is essential. Slow to establish...A classic older
introduction but never bettered."
Similar cultivars include H. 'Blue Dome', H. 'Blue
Velvet' and H. 'Skookumchuck'.
