Answer: Lisianthus (Eustoma grandiflorum), also called Texas Bluebell, is a short-lived perennial or a biennial in it's native habitat, but it's usually treated as an annual in other parts of the country, often being purchased in pots as two-year-old plants. Since the plant is biennial, it doesn't flower the first year after sowing, and once it flowers, the plant dies. You can save the seeds, but they are dust-like and very difficult to handle. If allowed to go to seed, lisianthus will self-sow directly in the garden and new plants can be dug and transplanted in the spring.
