Jon, you are right! Numbers aren't sexy!
And you are also wrong. UC Davis has the right to name these things, so where does this end? We all get the numbered cuttings, and name them what we think? We find random figs on deserted property, and we name them after the street we found them? This is where confusion begins.
I think you named Emerald Strawberry with an enticing description, but it is what it is. You want 143-5, you order that. UC Davis will not recognize Emerald Strawberry and they will not honor your order if you use that name.
