What state are you in? All zone 8's are not created equal. I am going to say that overwatering is one of your problems. The tomato plant looks like "toast" to me and I would recommend starting over. The lettuce looks fine and the pepper should be on life support. Here in Western Oregon Zone Eight we are having unseasonably warm and dry weather. But it is still too early to put out unprotected tomato plants. Those nights when it was "37ish" it might have been colder in your garden and the tomatoes don't like a chill and will react as in your photo. (FYI: if you put your zone and location in your profile, it will appear on all your posts and give everyone a better chance to help)

It would help if y'all started a new thread for each new query. Include a picture (preferably showing the whole plant, a close up of leaves, and flowers if any), and tell us how big it is and where you found the plant. Knowing whether it's in Florida or Michigan can help ID a plant. Mary, I would say posting your three plants in one thread works, but piggybacking on another thread gets confusing, especially since others have done the same here. Also, there's a Name That Plant forum here; the people who hang out there are friendly and knowledgeable about a wide variety of plants. ----------------------- Now that I got that off my chest, the first one Mary posted looks like a carrot relative--maybe fennel or queen ann's lace. #2 might be a hosta relative. I think #3 will have yellow flowers, but I don't know the name. Maybe an artemissia relative?

hi peterson, thi fruit looks like some kind of orange it could be a grapefruit, my guess is that its some kind of a hybrid like the tangelo or tangor it cud be a cross between a orange(navel) and a grapefruit. ~HawaiiFruitGrower

I believe it is a echeveria agavoides, possibly Martin's hybrid. It is pretty. For care it is like all succulents, well draining soil, water only when dry preferably with rain water. Chemicals in tap water can be harmful. Acclimate to the sun slowly to prevent sunburn. Here is a photo of mine after some sun exposure.
