  Amorphophallus from Thailand
From: aroidgrower at verizon.net (John Ludwig) on 2007.11.02 at 00:17:42(16637)
I have seen a few species of Amorphophallus from Thailand offered on
eBay lately.

A friend told me that he had purchased some in years past and that

Which species? I can't think of any Thai species that have refused to
break dormancy for me. Maybe buying off eBay is the problem...

I purchased an imported A. pygmaeus tuber at the IAS show and sale in
September 2004. It did not emerge until this past spring - two and a
half years later! Each spring, it appeared like it was going to do
something (the growing point beginning to develop slightly) but it would
just sit that way and then shrink back towards late summer. I kept it
potted during the normal growing season, providing regular moisture to
hopefully stimulate growth, and when nothing would happen I would store
the tuber dry for the winter.

Despite this long rest, the leaf that finally emerged this year appeared
perfectly healthy and robust, and hasn't showed any signs yet of wanting
to go dormant.

Another species that I purchased that same year (2004) took about 18
months to break dormancy, but appears to be on schedule now.

I bought 5 tubers of Am. atroviridis this spring and had no "extended
dormancy" problems.

They were offered on ebay and came directly from Thailand via air mail.

4 of them were flowering this year, so I hope they will bring out leaves in
2008. One of them had a very badly damaged shoot, but after a while (I think
it was July) the shoot restartet to grow and made no flower but a leave,
which is still alive now in November!

I think these bulbs from Thailand can be bought, but it is a little similar
to the problems discussed here concerning the Turkish ebay seller
"ladybotany" - the sellers from Thailand use stolen pictures...., but the
big difference is, that you will receive your plants!

In the meanwhile I bought Amorphophallus bulbs from 3 or 4 Thai
ebay-sellers. I never had any problems, all tubers arrived in a good state,
sometimes even with the phytosanitary certificate.

They have very low shipping costs, and the prices for the plants are
moderate! The only thing I hope, is they do not run into their forests and
dig out everything they find, because of the momentary

Best wishes

I've never really had trouble with anything from Thailand.? You sometimes run into corms that can rest for 18 months or more even those grown here in the US.

Most Thai Amorphs have a pretty regular growth/dormancy cycle. But some species
are much more prone to skipping a season or two before either flowering or
up a leaf. Am. pygmaeus, atroviridis, and tenuispadix seem to be much more
to skipping a growth/flowering cycle.

Am. parvulus and Am. napiger, and a couple of other species that grow these
thin, long
tubers also might fall into this 'skip a growth/flower cycle'
pattern.........The reason I say
they 'might' fall into this category, is that many years their tubers grow out
of the bottom
of the pot and are broken off when the pot is moved, so it could be the damage
to the
bottom of the tuber that causes them to skip a growth/flowering cycle. I've
been trying
to keep some detailed notes on this hypothesis over the last few years, but
don't have
enough data yet to determine if my hypothesis is valid.

Ken, I did not know anyone was doing research on the effects of buying off eBay on plant growth. Can you send us some links to these studies?
I have had aoids sit for 2 years without breaking dormancy,and they are still very healthy mature plants. Some of these were from the IAS sale and some are growing wild on my farm in KY. I think it is mostly a result of environmental conditions. Like lack of rain or the tubers being disturbed during the vegetative growth cycle, as most wild collected specimens are subject to. Any info would be appreciated.
Thanks, Garland Bird

Amorph. albus - largest tuber bloomed in Zone 7 garden 2005. No leaf from that tuber sent up until this year 2007!

Hi James,

judging from the photographs it could be titanum, but many Amorpophallus
look like that when the leaf is still in the cataphylls. However titanum
has green cataphylls without any pattern and in that respect the picture
fits titanum.

Hi Bernhard,
I'm not sure if I had answered your email already, but yes, the albus (may be yunnanense but looks more like albus) which came from Kaichen in 1999 or 2000 listed as A-101, is hardy and proliferates here in my garden in NJ. As with some konjac and dunii tubers, the very largest may rot over winter. However I have had no problem with konjac blooming but yet to see a dunnii bloom and a repeat of the albus.
