Re: CalSibe fertile tetraploids

Thanks, Jeff and Carolyn.  I recall that passage in McEwen's book but could
make no sense of the version posted.  Tetraploid Calsibe seed was offered
last year by SIGNA and I have one very vigorous seedling coming along from
the four seeds I planted. Calsibes have been short-lived here in central
Virginia, as are both of their parent types (though Iris delavayi has been
with me for 10 years now).  I'm hoping the tetraploids might be more
adaptable.

I wonder if anyone has tried tetraploid calsibes with tetraploid 28 (56)
chromosome siberians?  A breakthrough there could lead to some really
exciting plants.
