For drosophyllum seeds the consensus is that you need to do
_something_ to damages the seeds coat. I normally used a knife to do
this, Manfred's idea of acid sounds like a good one to try and yours
about the tea gives me a readily accessible solution to try.
As for Manfred's question about the time the flowers last - from
memory I thought they lasted until pollinated. I think that
drosophyllum flowers may just self-pollinate but the bright yellow
flowers would certainly be very attractive to all sorts of things so I
think they get pollinated very quickly. I never had any trouble
getting heaps of seeds from my plants. You will know when the seeds
are ready because the seed case will go transparent.

about to break and we're wearing ... we're wearing ... sort of things,
like glass, only dark... dark glass things on our eyes..."
