This hybrid of H. 'Sum and Substance' ×
H. yingeri was
Greg Johnson of Iowa in 2004.
It grows into a medium size hosta about 12 inches tall with a spread of 34
inches with dark green leaves that have thick substance. Pale lavender flowers
bloom in July.
An article by Glenn Herold in
Hosta Journal (2014 Vol. 45 No. 1) states
that, "Johnson crossed H. yingeri with 'Sum and Substance' to get 'Old Coot' and
'Jaz'. Both have good substance and shiny leaves."
