Answer: I believe the Lisianthus (Eustoma species) sold by Burpee is the annual type. Annuals and biennials are physiologically programmed to die after producing seed. You can certainly save the seed, though! Sprinkle seeds on the soil surface in flats, and press them in, since they require light to germinate. Germination takes 10 days to 3 weeks given temperatures between 65-75F. Keep the seedlings very close to the growlights (within an inch), since these prairie natives won't grow well without intense light. Keep soil evenly moist with a plastic cover over the flat, or by using a capillary matting. Best of luck!
