Rusty,
J. Marion Shull who meticulously described the TB irises of his day in his
1931 book "Rainbow Fragments" noted leaf color using the following terms:
gl=glaucous, g=green, yg=yellow-green, bg=blue-green, d=deep (a modifier of
any of the preceding), and t=purple-tinged (glaucous refers to the whitish
substance on the surface of the leaf that gives the green of the leaf
itself a grayish cast).
By this sytem he classified the leaf color of SINDJKHA, for example, as
glyg=glaucous yellow-green
LORELEY was bgt=blue-green with a purple-tinged base
QUAKER LADY was glgt=glaucous green with a purple-tinged base
MADAME CHEREAU was glg=glaucous green, and so forth
The diversity of leaf color must be related to the diversity of ancestry of
TB iris. For example, I believe purple leaf bases are supposed to be
derived from I. variegata and I. pallida is known for its glaucous
blue-green foliage.
