This are Lilium canadense seeds in the first stage of germination. It is a delayed hypogeal species and has been in warm stratification (69 deg F) for 30 days as have the others. http://flic.kr/p/e3knc5/ Another delayed hypogeal species, Lilium michiganense, with exactly the same timing in warm strat as above. The bulb like structures at this stage of germination is interesting to watch. http://flic.kr/p/e3kn9m/ This species, Lilium philladelphicum, appears to be putting out a radicle rather than the bulb like structures above. http://flic.kr/p/e3knf7/ I've been checking these seeds in warm stratification every 7 days. I'll hold them in warm strat for another week at slightly cooler temperatures, then move to cold and watch carefully for 3 months. If the root continues to develop I'll plant in a container and hold in cool conditions until they begin to emerge. Rich
