jerusalem artichoke seeds, germination test

jerusalem artichoke seeds, germination test. cold stratified just on some damp paper towel in the fridge may 6-june 1 and then set on top of the fridge so room temp to germinate. today is june 10, and these are a few days old. you need to do this cold step for these and many perennial seeds to germinate, otherwise plant outside in early spring and the soil and nighttime temperatures should be cold enough. #jerusalemartichokes
