This second generation H. 'Tardiana'
seedling was another of those registered (1988) by the British Hosta and Hemerocallis Society (BHHS) on behalf of English hybridizer,
Eric Smith.
It forms a medium sized (13 inches high) mound that has bluish foliage in the
spring that changes to dark green later in the summer. Pale
lavender flowers open in mid-August into early September.
According to
The Hostapedia by Mark Zilis
(2009), "Though 'Kingfisher' is not as blue as many other
Tardianas, it does offer slug resistant foliage that displays a
rich green color from June to October."
