Got another plant I am not familiar with. It's growing behind a fig tree. In shade most of the time. It's flat and low on the ground, and it sends out many runners to start new plants.
Isn't there an app you can put on your phone to identify common and often, uncommon plants? Apparently it works with remarkable accuracy and is easily verified with an online search.
I phones have an ID built right in so when you take a photo you can look it up right away. Inaturalist is an app too.
When those apps come up with the right ID, it is indeed remarkable. On my desktop, which has a screen large enough that I can actually see what's on it, I like using Pl@ntNet (which I think I usually spell incorrectly when I mention it here), because it shows a probability for its suggestion being correct, which never seems to exceed 70%. I've had it show a 4% probability for an ID that was correct, and 50% returns for IDs that were off the wall. I've often (usually) tried that app, then posted here for better info. I've seen on Facebook a lot of what the iPhone app has returned. Based on what I've seen posted, it never really deals with there being similar plants, seems to just give one species or even cultivar, then goes off to something completely different for other possibilities.
