When should I start my Hosta seeds? Should they be sown inside first, then planted outdoors later?

Growing hosta seed is a simple procedure. Hosta seed sprout nicely indoors, under normal house conditions, with temperatures running 60? to 70?F (20?C). It is important that the potting soil/seed starting mix and flats or containers be sterile. Sow the seeds just on the top of the soil and cover with only one-eighth of an inch of potting soil. Keep the seedbed moist but not soggy wet. Hosta seeds you've collected yourself will probably have only about an 80% germination rate. Germination time for hosta seed will be about two weeks. Hosta seed does not require light to assist sprouting; therefore, you can place your flats in a warm, dark area of your house. When you see sprouts showing and breaking the soil surface, place the containers under fluorescent lights.
