I'm not sure it's malva. Looks like a weed in the buttercup family that I get in my yard.

Did you know there's a specific forum for IDing plants on gardenweb--called Name that Plant. Just fyi in case you weren't aware of that.

I did know that but I had never been able to post a photo so I thought I'd do it where I was most comfortable..(:

I just thought malva because it's only in this one place where I once planted malva..I should mention that the biggest leaves are about 5". Does it still sound like your buttercup weed ?

p.s. I'll post at name that plant too now that I know I can do it...

That doesn't look like any buttercup I am familiar with. Thing is it looks familiar - it does actually resemble a malva (mallow) hmmm...

I went and looked up pictures of the mallow. It's also called French
Hollyhock (which sounds better) I'm pretty sure that's what it is now.

I guess it's biennial which is why this huge crop didn't happen
till now. The kind I planted is Zebrina. I had no idea it went so nuts!
I have tons of them and I already pulled a ton out! I guess I'll just wait and see if it blooms...I have them sprouting up in sidewalk cracks and in between rocks and everywhere.

p.s. I also have this, I think, creeping buttercup, that I planted and it IS a weed. I planted it in my rock garden 3 years ago and it has completely taken over. It's covering the whole garden (about 12x8ft) So, if anyone wants to cover a big area fast plant that. It has cute yellow buttercups all over it that are bloooming now. But I think I'm going to have to start my rock garden over.

The biggest leaves are 5 inches not 5 feet, of course..

Just be happy those Zebrina's are annuals. You just have to watch the seed production to keep them under control. I usually end up pulling them before they are done flowering because of the multitude of seed pods with multitudes of seeds in each pod.
