This species is the focus of some differing opinions. Two forms
of the plant were found in
Japan and they were given different
names as if they were naturally occurring forms of a single
species. Here is a brief summary of the debate (as I
understand it anyway).
One of these hostas was known as H. rohdeifolia forma
rohdeifolia. In the book
The Genus Hosta by
W. George Schmid (1991), it was determined that this plant did not come
from the wild but, rather, came from cultivation. Therefore, it
was "downgraded" to cultivar status and is to be known as H.
rohdeifolia 'Rohdeifolia'. It is not a species. In the
The Hosta Handbook (2000),
Mark Zilis feels that is actually the true species, Hosta rohdeifolia.
The other plant was named H. rohdeifolia forma viridis
and was known in
Japan as the "green-leaved hosta with leaves
like Rohdea". Schmid says that this is the true species,
Either way, we are talking about a medium size hosta (14 to 16
inches high by 12 to 16 inches wide) with a generally erect
form. It has dark green foliage that is slightly convolute,
oblong-lanceolate in shape. The pale purple, funnel-shape
flowers with light yellow anthers bloom in August.
The Hostapedia by Mark Zilis (2009), "...the plant grown as H.
helonoides albo-picta...was actually H.
rohdeifolia. In the ground, it has a rapid growth rate and
is a great choice as an edging plant."
