Answer: Some seeds are programmed to germinate after certain climate conditions are met. Lavender prefers a period of cold. This is termed "cold stratification." You can simply put the seeds in the refrigerator. Sometimes gardeners will sow seeds in pots and leave them outside in winter (if cold enough) for the appropriate period of time. Most of us don't have enough space in our refrigerators to put plant pots in there!
