Answer: Congratulations! It's not easy to start Eremurus from seed! Are you also a patient gardener? I ask because Eremurus can take 6 years to blossom from seed.
While they're in the seedling stage, try to keep the air temperature between 10-15C, which helps them grow evenly. After danger of frost has passed, plant the seedlings in a nursery bed, and in late summer, you can transplant them to their permanent location, in deep (.5 m), rich, organic soil, in full sun. Hope this helps!
