It sounds like a type of euphorbia -- but am not sure. I have several on my patio in pots right now and they vary with and without leaves, with and without spines and with and without flowers. They are a type of succulent and my thought is with the leaves you are not likely looking for a cactus. Look at some of the euphorbias on the wikipedia page or just do a google image search for euphorbias and see what you come up with. Here is a link that might be useful: Euphorbia

you better have put it outside.. in full shade.. until it hardens off to sunlight ... but lets be clear ... its an ANNUAL up here in MI ... i am not looking up its native proclivities ... nor do we know where you are .... but my point is ... its not a plant you will have forever ... just because your boy gave it to you ... if it blooms.. gather some seed ... and try to get a full ID when in flower.. buy some seed.. etc ... and keep a plant of this type alive ... it can all be a learning lesson for you and the boy.. about how mom can have this plant forever .. but perhaps not his specific individual ... i remember all these grade school projects... and kids bringing home things that wouldnt live .. lol .. heck.. half the pine trees planted one foot from the house.. that are now 50 feet tall ... were darn arbor days gifts from the schools ... lol cherish it.. relish it ... but do understand.. all about it .. good luck ... ken

ha ha jokes on me ! I read your post to say you were looking for id's on 3 of them . My only excuse would be ......well no excuse . I misread ,it's as simple as that . No problem , If you know who they are that's great . I have some I wish I could id many thanks to my dogs for running off with the tags and chewing them up. Here's some examples . Anyone want to hazard a guess? The one I really want to id of course I cant find the picture of at the moment . I will keep looking for that picture . Oh and one last thought, jo_pyeweed don't you dare stop posting !!!!!! Who am I ? only clue I have to this yellow one is that it blooms in end of May in my zone 6 and is about 2 feet tall here , does anyone think this could be Custard Candy ? Found the other image I was looking for . Anyone know this plant ? It's a shorty ......maybe 23 or 24 inches tall.
