GROWING FROM SEED: 
You can also plant lavender directly into the soil in the fall and wait for it to sprout in the spring. Just remember to mark where you put the seeds, so you don't mistake them for weeds. Once the seeds have sprouted, they need to stay warm and have lots of light.  Lavender Seeds can take 18-28 days to germinate.
