Jim- congrats to you and yes  OP hybrids are something we need to be thoughtful
about  Very sound suggestion..  These plants sound great.. hope fertile for you.

Curious as to how your Kaichens did and how your season has progressed.. After
a terrible dought h last year, lots of plants retrogressed amazingly to juvenile
and lost some old old standbys.. most of a big angust. penn varieg patch
including my best big female. Rats! Also  lost some to a tough winter apparently
including all circa 15  franchetianum.! I  some would have made it  in reduced
size if it had been dry conditions only.  I guess they're not very hardy..
Strangely Sauromattums look fine!
Ironically now that I have a new powerful well, we"re having tons of rain  this
year. Zero days over 90 in july  too , in marked contrast to last year. Presume
you are in similar condition or are you  also picking up the dry hot weather
from the south as well?
Thanks for Kaichen info . This year I 'm going to be much more selectivein
ordering due to heavy mortality.  Had about 40% of species finally sprout in
pots of kitty litter held dry in garage until sprouts started or to May, then
transplnted to richer garden soil on sprouting strongly..Then maybe too wet, but
I suspect fungus with bulbs caused too many to leaf out , then loose top growth
after a week or 3...too fast for normal.  Well, will hope for reappearance in 01
but  suspect the worst.  Is it that the bulbs are too super scrubbed and rough
handled? Did you have similar?
One of my 98 Dysosma difforme that had 6" velvety  hex leaves last year
converted to 12" shiny black and silver and green like some odd
turtle. Super I'd like to try for more odd Dysosma and Paris.. Lost  nice cut
-leafed Dys #1 last winter. Paris # 2  nice sturdy green  ...good stuff....but
which Arisaema to shoot for out of so long a list?.  I definitely need to look
at photos! Have you found any goodies?  All the very best.  John
