Every plant in your nursery has a name, and that name is doing more work than it looks. It is on the label, the delivery note, the invoice, the passport and the order. People read it and assume that if two documents say the same thing, they describe the same plant, and that if they say different things, they describe different plants. Both assumptions are wrong the moment a name drifts.
And botanical names drift constantly. A genus gets revised and yesterday's Coleus is today's Plectranthus. A cultivar is abbreviated three different ways by three different people. A non-breaking space, a stray capital, a translated common name typed in instead of the Latin: each one is invisible to a human reader and fatal to anything that matches on text. A search for the old name returns nothing. A report splits one line into two. A passport claims a plant that, on paper, no longer exists.
It is a traceability failure dressed up as a typo. "One step back, one step forward" only works if the thing in the middle has a stable identity, and a free-text name is the one part of a plant record that was never built to be stable.
