Can anyone tell me the difference between Dipladenia and Mandevilla? I am looking for a thriller plant for a container with bright pink flowers and bushy (not a vine). We get a lot of tropicals in from Florida but honestly I don't think our local box stores or garden centers have a clue. They are just trying to make us plant shoppers happy. One option would be to put a trellis in the pot and go with a pink mandevilla if I can find something more bushy.
