How to cold stratify dodecatheon?
Hi there, I would like to establish some Dodecatheon plants under a beautiful old apple tree so that they flower in spring 2021 (I'll be moving house after that so would like to see them in bloom once before I go!). My seed packet suggests cold stratifying them (I'm guessing to force them to bloom sooner than they naturally would?). I have no idea how to do this and online guides vary in technique - does anyone have any experience doing this with Dodecatheon? Cheers!
