I planted dahlia tubes in march and these just popped up a 2 months ago. They are growing in a spreading method and not upright.

Looks like purslane

While the overall plant habit is quite similar to purslane, the leaves in the photo: 1) are too small relative to the stems; 2) seem folded like clover leaflets (purslane's leaves are flat); 3) are too wide in relation to their length to be purslane; and 4) do not appear to be succulent leaves (as purslane is).

In any case, it is not a dahlia.

I can't see it well but had thoughts of Euphorbia maculata and Pilea microphylla. What state or country is this in?

RE: is this a dahlia sprout or a weed?

The stems are too thick to be Euphorbia maculata -- and there's too much going on there (flowers, etc.) to be E. maculata (or the similar weedy Euphorbia which isn't spotted).

I don't know the Pilea, but apparently it's not prostrate?

Jazer80 - would you post a close up (or two?)

RE: is this a dahlia sprout or a weed?

This is the close up. I'm going to keep it and see what becomes of it. I planted wild flowers and dahlias in this pot. Everything died from the heat wave t. I live in Los Angeles California.

Can you get closer, so there are maybe only four or six leaves in the photo?

Hope this is better

The leaves are heart-shaped and folded.

An amaranthus, I think.

Amaranthus blitoides

Amaranthus blitoides, I believe. Prostrate pigweed.

Jazer, it's always helpful when you post the location of the plant - city/state, growing conditions, etc. You see how I've got my city & USDA zone included near my name?

Here is a link that might be useful: Prostrate pigweed
