large size (19
inches high by 55 inches wide) botanical form of the
longipes was found in
Dr. Fumio Maekawa in 1940. Its green leaves are slightly shiny on top,
very shiny on the bottom and are broadly ovate in shape.
It has dense clusters of pale purple flowers with purple
anthers borne on 20 to 30 inch scapes in August into
September followed by viable seeds.
The Hostapedia by Mark Zilis (2009), "This form differs from H. longipes by having
green petioles, i.e. no purple-red dots."
The New Encyclopedia of Hostas by
Grenfell (2009) states: "Very variable in the wild, where many natural
sports and seedlings are still being found. Many
botanical forms are much used in breeding...A nearly
flat, overlapping mound of wide leaves."
