Re: Alvim Seidel Philodendron seeds - questions

From: Todd Ruth <truth at weber.ucsd.edu> on 1997.03.20 at 00:29:00(514) 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 +More 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. adamantinum Cost per 1000 seeds: $15 Size: Medium Notes: Needs strong light.
