Re: Alvim Seidel Philodendron seeds - questions


Well, I took the previous posts, info. Tom Croat sent me, and everything
I could get out of the Sunset Western Garden Book and made an html
formatted document.  Qualcomm isn't allowing the creation of new web
pages right now, so I can't put it up anywhere, put I'll include it
at the end of this message.  I think it is fairly readable, even though
it's filled with tags.  If you save this message and cut off the top,
you can view the rest with lynx or netscape or whatever.  If anyone
has any additional info. or corrections to what's here, please let
me know!  Much thanks to those who have provided info allowing what's
here so far!

Thanks,
Todd

PS  "SWGB zones" listed are quite different from the standard zones.
    Zones 8 and 9 are the cold-air basins and thermal belts of
    California's Central valley.  Zone 12 is Arizona's Intermediate
    Desert.  Zone 13 is Low Desert - Mildest of Desert Winters.
    Zone 14 is North. Calif. Inland areas w/ occasional ocean influence.
    Zones 15 - 19 have typical winter lows of 18 - 25 F and Zones 20 - 24
    have typical winter lows of 23 or higher.  I can't describe their
    zones in a few sentences because they involve many factors.
    Hopefully, that at least gives you some idea of what is meant.

All need to start warm and humid.  Entries which do not contain
a line regarding species name are labelled in agreement with
the current practice among taxonomists.  SWGB = Sunset Western
Gargen Book.  This is a great book for the garden, but does not
specialize in aroids, so I'd especially like confirmation on
anything with SWGB next to it below.  I've left obvious misnomers
in SWGB notes in place because they concern morphollogical differences.
I've heard that the difference between arborescent and self-heading
is in the eye of the beholder, but I've included the distinction anyway.
