Whenever I read about a new seed that's troublesome to purposefully germinate, but yet self-sows, I now immediately ponder whether or not it needs a warm period before being cold stratified. It may be that some Tricyrtis seeds follow this course. I have some coming in as well, so I think I'll match them up to the ones listed on
Tom Clothier's site and follow that lead. If the seeds come in time I may even be able to meet the cold temperature range outdoors, although a guideline of "24-39ºF for 4 to 6 weeks" may be difficult to hit, as currently, we're hovering near zero, and will fall well below that again tonight. February can be similar here, but maybe the second half of it will warm just a bit.
