ICPS seedbank has this to say:
Does anybody here have any advice on how best to germinate these suckers?
I live in Houston. I have a growth chamber that gets up to 90 deg F on the top shelf.
For those who have successfully germinated the seeds of this particular variety,
* what size pot did you use?
* what soil mix
* pre-germination conditions?
* how you did the warm stratification
* scarify or not?
* carefully controlled terrarium conditions, or outside, and let nature do its thing? (I'd be afraid our frequent torrential rain would wash away seeds...)
