Interesting.  I bought bulbs of Gladiolus Boone from an Old House Gardens
many many years before.  I like its smaller size and
old fashioned yellow color tone for my arrangement.  Later I found that
they were naturally (?) hybridized in old house somewhere in NC.
Cases Cove in NC is the place for original G. boone?

I bought G. dalenii seeds from Silverhill  Seeds many times to make my own
G. boone, but no progress so far.  G. dalenni has wide color variation from
green, red, orange and yellow.
G. gandavensis that you saw in SC must come from the ancestor, red color G.

I wish to share some bulbs of G. gandavensis red in SC and G. gandavensis
yellow in NC.

I could not find the picture of G. gandavensis that you attached.
