Lupine seeds have some very specific germination requirements. Seeds need a soaking to soften the outer seed covering, and a 4 week pre-germination chill, so they are best sown in fall to overwinter and sprout in spring. They grow in a wide range of soils in full sun. Or, you can soak the seeds, then mix them with moistened growing medium, place in a plastic bag, seal the bag and refrigerate for 4 weeks. Then remove the seeds and sow 1/8" deep in a prepared garden bed in spring. They can take 15 to 60 days to sprout. However, once they are established in a garden they tend to self-sow readily. Good luck!
