Can you zoom in on those two flower bud/seed pods? Do I see tendrils? And give an indication of whether this is an indoor or outdoor plant? And where in the world it is?

ooh -i just gave it away (i will try to get a photo later) i bought it in Greece, i was told it has mauve flowers and it trails across the ground -

Cymbalaria?

This seems to be clearly showing a viney phenotype; that Aussie violet isn't named hederacea because it twines.

There is a hairy subspecies Cymbalaria, Cymbalaria muralis subsp. visianii, although I admit it doesn't quite look like that either.

I rarely resort to AI (why bother when we have floral and jay around!) but it suggests...

Dichondra argentea, Centella asiatica, or Hydrocotyle. None of which I feel wedded to!

That Cymbalaria muralis subspecies still has the same tiny leaves. They're no bigger than my fingernail. Honestly, nothing like the OP's plant.

Not wedded to the Viola, but it does produce runners. https://share.google/4UiqLiIbVPdXh1rW2

Mea culpa! Not AI's fault - wikipedia's description is missing anything about runners! https://en.wikipedia.org/wiki/Viola_hederacea

That has to be what it is. Glad it's not in my lawn - violet is a bad enough weed as it is. (was just spraying some today!) I can easily override my fascination with antipodal plants to say I never want to grow that.

FWIW C. pallida is said to have leaves much larger than C. muralis, but I don't think its that one either.

Viola hederacea is a complex and some newly classified species have been named out of it. The variance in leaf shapes allows for perfectly round leaf shape, lacking the ivy-like 5 divisions. Can you give some backround about how you obtained this plant? Hydrocoyle also have round leaves, peltate stems and sometimes runners, but this looks more like Viola to me.

Pennywort.

bought it in a small shop in Piraeus Greece, no label, i was told it had mauve flowers, i have given it to a friend i will take a look at it later if possible. it looked like a Ipomea to me, but i get a lot wrong :-) thank you for your reply, i appreciate all the help.

In Greece Viola hederacea is sold as Viola banksii. V. banksii is one of the new species taken from the V. hederacea complex. There are many different colored cultivars, with some having mauve centers, and breeders are coming up with some one colored types. It's uncertain whether or not all these types sold in Greece are actually V. banksii, or another entity from the hederacea complex. Pilea peperomoides has perfectly round leaves, peltate stems, and mauve "flowers", but no leaf sinuses. I don't think any species in Convolvulaceae have perfectly round leaves or true peltate stems?

There's a seedpod visible which looks violetish too.

yeah the violet makes sense now that I know there are some that have runners, which might be giving me nightmares soon
