Coreopsis might be another possibility. Close-up definitely needed! If you are just trying to copy what somebody else grew (ie the photo isn't of your plants), just pick something easy and yellow that you like. Marigolds are a nice, easy choice. Nasturtium is another. I personally would choose calendula. FataMorgana

1) Coreopsis. Sweet lil plant. Deadheading will lenghten bloom period. Late season I let some go to seed. 2) Stokes Aster. Great flowers but I've never had luck keeping the plants going more than 2 years or so. sigh... 3) Deadly Nightshade. Rip it out. Rip it out. Rip it out!! (Can you tell I deeply dislike the stuff?) ;-)

Looks like a mandevilla, sometimes called dipladenia. The blooms are usually pink, red, or white. Yours is striped, so I think it's a fairly new variety called 'Stars and Stripes'. I don't think they're ever yellow....the man you talked to may have been thinking of an Allamanda, which is a different genus, but a vine in the same family. It also has five lobes to its flowers. People in my area (SW Indiana, zone 6) grow mandevilla as a summer annual, but lose them with the first hard frost. I don't know of them coming back after even an average winter. I'd keep it on a sunporch and not try to overwinter it outdoors since they are subtropical.
