Gator, if it was me sampling the leaf I would most probably would know what it is, lettuce, collards, mustard, taste completely different and also have a different texture and even different colors in the shades of green. Did you by any chance planted oriental greens? they can taste milder like a lettuce. I have about 10 different varieties and some taste like cabbage, others like lettuce and others a little bit like a mild mustard.

Do you compost? I've had tomato plants come up in the compost from throwing tomatoes in it when they start to go bad. I don't know what kind of green that is, looks like lettuce though.

It looks like mustard to me too. Is it sort of spicy tasting? Be careful of eating mustard raw. It has oxalic acid crystals in it that can mess with your kidneys. Do you eat tomatillos? That's what the "tomato" plants look like to me.

You guys are so savvy. Thank you for the responses. I am convinced this is a mustard green. I can't believe it -- I know for a fact I have never in my life purchased mustard green seeds. And, yes, it was quit spicy tasting (I did not swallow any).

As for the "tomatoes," I think we are right that they are tomatoes. I don't compost but I do move my container soil around a lot and often rotten tomatoes have ended up in the mix. I bet that's what is going on. I will let them go and see what variety they are. I hope they're one of the good ones!

I love garden surprises! I have six baby 'maters growing right now that came up in a dried up six-pack a month or so back. I can't wait to see what they are! They may be nothing, or they may be some heirloom seeds I spilled when I was planting.

Did you ever buy anything like Johnny's Oriental Greens mix? I was thinking it looked like the Chinese mustard from that.

You know I did have a mix that was mesclun, but I don't think I used it and this plant seems too big to be mesclun.
