I've just been given fruit of Anchomanes difformis and Arisaema triphyllum.
Never having grown either from seed I'm hoping someone out there can help.
--My plants are now dormant. Should I wait until spring to plant?|
--Any suggestions for seed mix?
--Same questions as above, but should I refrigerate the cleaned seed? If so,
for how long. I am in Central Florida. This sp. will grow here but is
native to the northern part of the state which is colder.
Many thanks in advance for any advice provided!!

According to Rob McClure (my seed source), these seeds need warmth and
humidity to germinate. Living in Wisconsin and not wanting to wait until
next August (!), I've got them in loose compost in a glass jar in one of
the 37C incubation chambers in my work lab. I don't know how long the
seeds are viable. There was also a note from Wilbert that once germinated,
these plants will put up multiple shoots from the developing tuber until
finally entering a first dormancy. Evidently the roots are rather fleshy
and do not like to be dried out during dormancy (Hope I got this right,

I harvest my A.triphyllum seeds in October and keep them in coarse peat in
a baggy in the 'frig until spring. I don't know if there is any minimum

Thankyou so much. You've answered all my questions!!

Nearly all Arisaema seed do not require a cold period to germinate. A.
I use the Deno method for seed germination, so the media is a scrap of
wet paper towel.
Once the radical emerges, carefully transfer the seedlings to any sterile
mixture and keep them moist.
You will probably have some problem growing the plants to best advantage
because they do like
a cool period when they go dormant. It doesn't have to be really cold
although we really
don't know exactly how cold it has to be. My guess is in the 50F range or
In the north, we lifted tubers like Glads, etc. and stored them nearly
dry for the winter. The same will work
in the South for Arisaema storing them in the refrigerator. But, what we
really need is a good
study with a range of storage temperatures and times including control

Thankyou so much for the input. A. triphyllum will grow and bloom easily here,
but I've not seen fruit. However, I thought seed might require chilling and
am glad to learn that it doesn't. We're growing them in our camellia beds.
Normally, the temp will go down to freezing at least once a year, but often
there will be warmer or far colder years--17deg F is the coldest I've seen.
Perhaps this will give you a feeling for our 'range'. The plants are left in
the ground all year. They would probably grow 'prettier' with the
refrigerator treatment and I haven't studied them to determine if they perform
better after cold winters. Must try a study---when someone provides more
hours in the day!!
