There was in fact one setosa x PCN offer.  "canadensis x west coast" is I
suspect a cross within setosa itself.  I could not find (quick search) any
record of previous setosa x PCN hybrids, and given chromosome numbers it
would be unusual but not impossible.  PCNs cross with 40 chromosome
siberians, and recently sibtosa hybrids (28 chromosome siberian x setosa)
have appeared.  However, the cross of 40 chromosome x 28 chromosome
siberian is difficult.  A few are known and evidently some are fertile.
These might be crossed to PCNs and then the offspring to setosa.

Sounds interesting, but sometimes SIGNA seed does not turn out to be what
it is supposed to be.  A few years back, I ordered and grew some
"tetraploid" tectorum from seed.  They looked just like ordinary tectorum
and pollen measurements confirmed that they were diploid.  Likewise, seed
of "I. koreana" turned out to be plain old I. sanquinea.  SIGNA can take no
responsibility for this and should not be expected to--they just pass on
what seed donors send them.

Has anyone else tried the various biversatas ((ensata x versicolor) x
versicolor) offered through SIGNA?  Mine bloomed last year and were very,
very close to pure versicolor.
