Does anyone know what it is?
Nasturtium / melon / annual ?
Nasturtium or hardy geranium?
I think it's one of the Malvas.
Not a nasturtium. ( predictive text replaces nasturtium with an interesting alternative!)
There's another thread with this one on.
I think it's Malvaceae/lavatera and probably annual
Nutcutlet, I think I may have posted a similar unidentified plant - I described it as a geranium with no geranium smell. I have 3 Mallow (lavatera) plants already in my garden and the leaves are textured, kind of hairy but the photo I shared which is very similar to the one in this post has no texture in the leaves. Could it still be a Malvaceae/lavatera?
