Actually I have had pretty good luck in my attempts with tuberous Drosera
seed! :-) I got all mine from the seedbank though, so it's likely they
were harvested from cultivated plants.

On the other hand there are many quick-germinating desert plants. Not just
annuals, some true xerophytes like Stapelia and Pachypodium have have
quick-germinating, short-lived seeds.
I believe the Australian climes inhabited by tuberous Drosera are radically
different from our Arizona deserts. Just sprinkle some D. ramellosa seed out
by Ajo and wait! :-) I wonder if fire plays any part in the germination of
tuberosities?
