Hosta 'Sum and Substance' is the
classic giant sized hosta. It forms a giant size (36 inches high) clump and is used as
a specimen plant in the landscape. It was registered by
Paul Aden in
1980 but the parentage is not know.
The leaves are moderately corrugated,
have deeply lobed margins, are cupped both up and down and have a
long, distinct tip. It has thick substance which makes it
resistant to slug damage. In late July and into August, it
produces large pale lavender flowers on four foot tall scapes.
