This non-registered but patented (U.S. Plant
Patent 14,232) cultivar is a sport of Hosta sieboldiana 'Elegans'.
It was introduced by Allen Rick Crowder in 2002. The mound reaches large size (21 inches high) with leaves that are heavily corrugated, wavy and somewhat unruly but
with thick substance. Near white flowers bloom in mid June to early July.
According to
The Hostapedia by
Mark Zilis
(2009), "Information published by the U.S. Plant and
Trademark Office lists 'Thunderbolt' as differing from the similar 'Dream Weaver' by having a wider margin and more "deeply furrowed"
leaves...Unfortunately, try as I might, I cannot see any difference between the
two and do not agree that 'Thunderbolt' has a wider margin. I'll keep studying!"
Similar cultivars include H. 'Dream
Queen' and H. 'Great
Expectations'.
