Cynthia, in my experience, Lycoris sprengeri sets viable seed. Is it self fertile? I can't say for sure, because I don't know if the stock I had was clonal or not. I suspect it was clonal because it came from a local nursery which propagated its own plants in a small way. I doubt that they were waiting six or seven years to get a blooming sized Lycoris from seed, so I suspect that they were dividing them and potting them up separately.
