Answer
Cynthia:
Growing lavender indoors need full east sun.Need also bottom heat.Artificial light should be 2-tube 1 warm light 1 cool light tubes.I don't know about how long seed from lavender last. I know the dutch lavender last a long time. Plant in well drain soil with lime added each year. Prune each branch by 1/3 from the top down,every 3 weeks during the summer & fall.I hope this helps. The lavender named Provence,Grosso has the best scents.
