Diana Grenfell from
England registered this cultivar in 1996 as a sport of H. 'Sum
and Substance'. It is a giant size (33 inches high by 78
inches wide) plant with gold
leaf margins and 15 pairs of veins. Pale lavender flowers bloom from late July into August.
The Hostapedia by Mark Zilis (2009), this cultivar "...was the first green-centered sport
of 'Sum and Substance' to be widely propagated by
tissue culture. Its margin is noticeable but narrow in comparison to
several newer cultivars."
The New Encyclopedia of Hostas by
Grenfell (2009) states: "...adequate moisture will encourage deep
seersuckering and puckering of the leaves...Yellow margins of similar cultivars
are said to be visible earlier in the new season's growth, but once they are all
in full growth, there is virtually no difference in the width or the color of
the margins. Lovely with orange daylilies but impressive as a specimen in a huge

An article by Warren I. Pollock in
Hosta Journal (1996 Vol. 27 No. 2) states that, "I wrote
about the exciting new sport of 'Sum and Substance' named 'Lady Isobel
Barnett'...The leaves are thick, glossy dark green with an irregular narrow
creamy-yellow margin." Pollock went on to identify other 'Sum and Substance'
sports with similar leaf colors including H. 'David A. Haskell' and H. 'Sum
An article by
Warren I. Pollack in
Hosta Journal (2020 Vol. 51 No. 1) titled
Doppelgänger Hostas: Fancy Name for
Look-alike Hostas, included a long list of hostas
which various hostaphiles, published articles or other sources have
indicated "look" the same. Some of these are, in fact, the same
plant with two or more different names. Others are hostas that vary
in some minor trait which is not immediately discernable to the
casual observer such as seasonal color variations, bloom traits, ploidy, etc. So, as Warren mentions, hostaphiles may differ as to the
plants listed but then, their opinions are based on visual observations and interpretations.
'Morning Light' is included on two look-alike lists in this
article. Following an algebra rule I learned in the last century, if
A=B and B=C, then A=C so all the hostas on both lists should be
List #1 - H.

List #2 - H.
