Jim The storage roots are generally obvious on S. latifolia though usually deeper in the soil that the rhizome, but the other species of Sag in my area (northern Florida) don't produce those tubers. I don't know if there are other species in Dennis' region, but it reminds me most of S. lancifolia in my area. I hope it does get so we have to eat those, but at least they are easy to grow prolifically if we do! They don't taste great but at least they are not very bad tasting. Better figure out some sources of decent spices to jazz them up! Alani
