This popped up in my garden, which was formerly part of one of our hay fields. It's strange looking! I've got another one that I'll post next that looks very similar, but different enough that it may be a different weed.

This one is growing in bark that is on top of weed block, so it must have started from seed. I was thinking at first that it could be a spurge, but there is no milky sap when I break it apart. This particular plant is 9 inches across, but I doubt that it is done growing. I can't find one that is blooming, so I'm not sure what colors the flowers are. I'll keep checking on it though.

Any suggestions would be most appreciated!

It looks like Miner's Lettuce too.

That is what it looks like to me too.

Yummy!

Thanks Daisy! I can't find any pictures that look exactly like this plant, so I wonder if it could be something else?

This does look somewhat unusual growth pattern. The center of the rosette looks slightly flattened and the flowering stems are growing out laterally instead of upright. Perhaps fasciation. It looks very healthy nevertheless.

That's what I thought too, fasciation.

Fasciation is a word I can't remember ever hearing before! I looked it up, and at least I've seen it before, but only on some blooms. Not sure how it applies to this plant, which I've been calling a weed, but I guess it is a vegetable? I posted pictures of another plant/weed/veggie that is growing not too far from this one (The thread "Crazy Looking Weed #2" in Plant ID forum), and I have a few more of those that look identical. This is the only one I can find that looks just like this. Its roots aren't even in any soil, from what I can see without disturbing it too much. It's just growing in the mulch that is on top of the weed blocking fabric. Would that have something to do with the way it is growing maybe? It is rather flat, maybe an inch or two high, but the other one is growing upward, at about 6 inches so far. The shape of the leaves on the two plants are different, so I'm not sure if they are both Miner's Lettuce or not.

I haven't gotten up the nerve to do a taste test yet! With my luck, it will end up be something that I should be wearing a hazmat suit while I'm around it, like some of the other scary things that grow here!

I really appreciate the help!
