>From MY experiences ( istress this as we all work different ways)......
Every Arisaema seed I have ever sown via the Deno method has not
germinated.  Just a straight fact from my own experience.  I know others
who swear by it.... me I swear AT it <grin>.

I use the same methods for my Arisaemas as I do for all my other bulbs,
jsut in a different place.  I sually soak the seed for a day in fresh wat=er
(tap water is fine here but obviously it depends on your tap water).
During this time the seeds usually swell significantly.

Next I fill a small pot with a good quality seed raising mix to about 1cm
from the top (after the pot has been tapped on the ground to settle the
mix).  I then sow the soaked seed onto the top of the mix, pressing them
very gently into the surface just to make sure they are stable.  Then I
cover with fine gravel (3-5mm grain size) to just below the rim.  The
gravel serves both as a mulch to stop the surface drying out and to keep
down weeds (not relevent in this case as they are in a terrarium in
controlled conditions).

They are watered and then put into my terrarium under lights (warm and
humid).  Using this method they usually start germinating in around 3
weeks.  Some take considerably longer and I have had a whole swag germina=te
at one point, only to have more germinate a couple of months later.  It i=s
up to the seed what it feels like doing <grin>.  Last year with the AEG
seedex I actually received some seed that was germinating in the mail.....
I treated this exactly the same way just without the soaking (which it
obviously didn't need).

This method was suggested to me for sowing bulb seed.... I just used the
same for the Arisaemas and it worked.  They then stay in their community
pot until they go into their first dormancy.  I have not yet repotted any
Arisaema seed in its first year.... I don't want to disturb their roots a=t
all as I want to get them as big and healthy as possible. Most commercial
seed mixes have a little fertiliser in them as well so they have food.

Is that a help?  I'm just trying to outline what I do so that you know th=at
you don't HAVE to use the Deno method for germinating.  I hope this is of
some use to you (and anyone else who is reading)
