I've had excellent results from dried exchange seed of both trillium 
and scoliopus. In fact, I sowed Scoliopus bigelovii last year and got 
100% germination (8 out of 8 came up).

My secret, if it is one, is that I always give seed a long soak in 
water before sowing, and then put the pot outside in a coldframe -- 
no fussing with temperature regime for me.

This method does not work with non-geophytes like the Labiatae
that simply want a modicum of warmth and moisture to germinate, but 
it works very well with a lot of geophytes and many hardy perennials.

Nor will I claim that this method always gives good results. A lot 
depends on how the seed was handled before I received it -- was it 
kept under refrigeration, for example?
