Hi @maipaismaven, welcome to the forum!
Looking through those observations, your photos are great and I don’t see anything “wrong” with them. The word wrong is a bit subjective anyways! I do want to address the broader question of “Does no one on iNat ID flora.” It might seem that way sometimes, and you’re not the first to hear the crickets on plant observations. Why? Well, I think there are multiple different factors at play here.
A mole cricket, just because it’s kind of cute and I mentioned crickets.
First of all, iNaturalist activity varies a lot depending on place! Some areas have a lot of naturalists, some of which are very active (Texas and California, for example) and so IDs will come in very quickly. Other parts of the world there are less people actively identifying observations, or less people with knowledge of the local flora and fauna. Many identifiers only identify within a certain region and don’t really ID outside of places they are unfamiliar with. Even within my home state of Texas that time to an ID can vary—a plant observation in Austin is going to get IDs much faster than one out in, say, Dickens County. There’s just fewer people online making IDs.
Who is active in the region where you post your plant observation is outside of your control, but hey at least you’re not posting observations on… um… Mars! Not that you can do that.
In areas with lower naturalist activity, you might have to wait longer for IDs. For example, here’s a plant I saw in Colorado that took nearly a year to get confirmed.
Second (as other people have touched upon), plants can be more difficult to ID. Some species are instantly recognizable without any close look-alikes. Then there are plants which might require more specific photos of certain parts for a species ID, those which might have so many similar species that only several experts ID them at a large scale (Astragalus, looking at you), and of course the plants which are more or less impossible to ID from the majority of images in iNaturalist observations, unless someone really clever makes a breakthrough (Tradescantia in Texas).
Ah, Tradescantia in Texas. So many very similar species which differ based on very-slight differences on the hairs on certain surfaces.
That all accounts for longer delays between upload and IDs coming in, and compounds with the first factor. You can ask around about certain taxa, as I did with the poppymallows in Texas. Identifiers are often happy to share resources or provide information to willing ears. That can help with getting ID’s for certain taxa.
Last of all, some plant observations simply don’t show enough to be confirmed, at least to species. Or rather, no one can identify a plant just from the photos taken, so they don’t. This is however something within your field of control, and often even minor things can significantly improve an observation’s chance of getting an second or third ID.
For example, one thing I would suggest you do is to take more photos per observation. Photos of flower backsides, leaves, flower closeups—these provide more information, and that is often very useful from the identifier side. Here’s another poppymallow observation of mine where one extra photo in particular helped a lot with the ID!

That was all I needed for that poppymallow observation to get a species ID. Not that I knew at the time, but hey, it worked! I got the ID!
I have “wasted” my time thinking about such observation improvements before and written a journal post on little tips which can help get more IDs on plant observations. Feel free to check that out if you wish.
Best of luck on your iNatting adventures!
