tardiva is a late-blooming hosta called Nankai Giboshi, the “hosta of the Southern Ocean,” for its habitat in Shikoku, Kyushu and Kii Peninsula of southern Japan. tardiva plants found in the wild are sterile so its species status is questioned. A large cultivar grown in North America under this name and illustrated in Aden’s The Hosta Book (1988; p. 32) with large leaves and 6–9 pairs of veins is not a  plant of this species.
