A vague tag is worse than no tag at all, IMVHO. And why does any tag need anything more than the name of the plant? The name is the key to any/all info about any plant. I wouldn't trust the info on the tag anyway, unless written by a local person.
It's in the sellers' best interests to put the names. Many people go searching for particular plants that they don't recognize if not blooming yet, and/or are susceptible to collecting names, or species of a genus. If I see a mystery plant and don't realize it's one I don't already have, I might not get it. The conditions at the grower/store usually cause the tiny succulents to look so much alike, but I know that after I take them home and give them much more light, their pretty colors can really manifest. If a name can confirm it's something I don't already own, my curiosity about observing to see how it's different will open my wallet. W/o a name, it may or may not be the same thing I already have. I have zero budget for buying the same thing twice because of vague or missing labels.
I didn't buy a mystery plant a couple weeks ago that I suspected was a Homalomena because it didn't say that's what it was. This is not a "wow" attractive plant we're talking about, but very generic and nondescript, plain green plant that had about 7 leaves; the kind of thing probably only someone looking for one would want, so it really could use some help being recognized. Although Homalomena is on my wish list since the old days of plant books with black'n'white pics, if I'd parted with $5 and ended up with some less common Spathiphyllum, I'd be very disappointed. I know I don't want any more of those at all. I have a small enough plant budget that I don't need to branch into mystery plants that may be something I actively don't want. I can easily spend it on accurately named specimens somewhere, never had a problem blowing the entire budget that way yet.
We seem to be in an age when people have lost the desire and ability to self-teach. In the "old days," when one had to go to an actual library *building* to seek the knowledge, or purchase ones' own books, it seems like people were more able to and interested in self-educating. I taught myself how to type, garden, cook, get taxes done, fix some things, do various crafts, filed a pro se bankruptcy, and other mundane stuff that's helpful to get through life because I wanted to learn and made the effort to seek the knowledge. I don't see people doing much of this anymore, and on garden groups on Facebook, people constantly ask the simplest questions that take longer to type than to google. Some of them don't realize the ARE ON the internet. It's flabbergasting! There is the entire world of info instantly available, and they don't even know they have it in their hands, let alone how to use it.
