 
Registered by
John Kulpa of Michigan in 1994, this cultivar is the result
of a cross between H. 'Kevin
Vaughn' ×
H. plantaginea. It forms a medium size
(17 inches high) mound of ovate shaped, slightly
corrugated foliage of average substance. The clump
has pure white, fragrant flowers from late July into
August.
 According to
The Hostapedia by
Mark Zilis (2009), "The variegation
pattern on 'Seventh Heaven' is highly variable,
often sporting to white-edged or white-centered
forms. Still, many collectors have been able to
maintain the true, streaked cultivar. Also, its
fragrant, white flowers are some of the largest for
a hosta other than H. plantaginea."
In an article in
The
Hosta Journal (2016 Vol. 47 No 2), the author
described this plant's flowers as having a "Strong"
fragrance compared to other hostas.

As
mentioned above, this streaked cultivar is highly variable and
the specimen pictured immediately above seems to have stabilized
as a marginally variegated type. A tissue-culture sport of H.
'Seventh Heaven' with this description was named H. '
