I've been obsessing on perennial onions for central Florida for years in this yard, have tried so many kinds that turned out to be either winter annuals or short lived perennials. I am now about 99% sure that "Eliska's Bunching Onion" IS different from my strain of Allium fistulosum, even just by looking at the two...mine as it divides makes stalks that at the outset are very thick and stout and leek-like....with "Eliska's" the divisions when young are VERY thin, like thin knitting needles. Plus it is VERY mild and sweet vs. mine is pungent onion. The bloom spheres on mine dwarf those of "Eliska's". So I feel it is very likely that we all now have access to TWO onions that are truly perennial multipliers in central Florida! And both are Mystery Onions!
