Thanks Rick.  The other places that I know of that grow Blyth intros
commercially are in Texas (?) and Keith Keppel.  Wonder if it freezes
often where Keith is now?

As for rot, these intros seem to be more afflicted with what we were
jokingly calling the molliegrubs - failure to thrive, major tendency to
sulk, iris tuberculosis ("wasting disease") at least in my garden.  They
sit there and gradually fade away, often taking several years to finally
die.  But before we go on that silly thread again, I admit I haven't
been looking at them closely for signs of pathology.  For all I know,
they may just taste better to crickets.

Phooey, trying to sort this out is impossible - too many unknowns.

(Jeff Walters cwalters@cache.net - this address doesn't seem to work for
me, but it was on your last post.  Any idea why it won't work?)
