This is a sport of the species, H. longissima, that was collected in the wild in Japan by Kiyoshi Kato. It was registered on his behalf by Wm Zumbar of Ohio in 1984. The narrow leafed plant has green foliage with yellow to white marginal variegation. It is a small size plant that bears pale lavender flowers in September.

According to The Hostapedia by Mark Zilis (2009), "...only differs from 'Asahi Sunray' in that its yellow margins turn to white during the growing season."
