Prairie Moon: C: (Number of stratifying days = 30): Seeds germinate after a period of cold, moist stratification (click for a picture tutorial on how to artificially stratify)

Mix seeds with equal amounts or more of… sterile media (moist—but not so wet that water will squeeze out of a handful). … Place mixture in a labeled, sealed plastic bag and store in a refrigerator (33–38°F). ... If two months (C(60)) of this cold storage before planting is normally required to break the dormancy of these seeds, one month may work for many species if time is a constraint. … Another method of breaking dormancy for species requiring moist stratification is to sow seeds outdoors in the fall so they may overwinter.
