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. 'Spring
while the other is a non-registered plant and needs
to be renamed to avoid further confusion.
A seedling of H. 'William Lachman', this cultivar was registered
by John Van Ostrand of Illinois in 2005. It forms a medium size plant with
medium gold foliage that starts the spring lighter and gets
darker as the season progresses. The leaves have a piecrust
shaped margin. Pale lavender flowers bloom in July.
MyHostas Database says that there is also
a cultivar of this name which was originated by
Stuart Asch of Michigan.
