Terry,
It's pretty hit and miss for me too (all miss at the moment
:-() but I think the day/night temperature has a lot to do with it.
>From memory I had the best success when the day temp was about 20 deg
C or above and the night temp was down around 10 deg C. I normally
nick the side of the seed and stand the seeds in water, I have had
better success when I added some sodium nitrate to the water as it
seems to stop the seeds becoming blobs of slime (dunno what it is but
it seems to indicate the seed is dead).

I know that one of the guys here in Adelaide could reliably germinate
drosophyllum by just putting the seeds in buckets outside but then it
stopped working - I reckon just about the time el nino stuffed up the
weather patterns here in Australia.

BTW Whilst I am on the subject of drosophyllum seeds - many thanks to
Loyd for sending me some fresh seeds. I haven't forgotten you!
