I have three lots of seed, two of Iris magnifica, and one of Eremerus himalaicus, that have been at 40F for three months, with no signs of germination. Should I move them to 70F, as I am doing with several lots that need cold followed by warm to sprout, or keep them at 40F for a few more weeks? All the other 40F for 90 days seeds I started this winter have sprouted, except these. Kathleen On the Pacific Northwest coast, where sweet coltsfoot, red currants and skunk cabbage are flowering.
