This is one
of those cases where there are two hostas with the
same name. One is registered and,
therefore, the "official" version of H. 'Green
while the other is a non-registered plant and needs
to be renamed to avoid further confusion.
This hybrid of
'Aureomarginata' × H. yingeri was registered by
Tony Avent of
Plant Delights Nursery in North Carolina
2005. It grows
into a medium size hosta about 15 inches high with dark green
foliage. In July, it bears deep purple flowers.
