The thing about trumpet fines is that they will climb as high as they can find something to climb. Technically, they can go 40 feet even, if they have something to climb. In most gardens, their height is limited to a trellis, but if you plan on planting it, say, on the side of your house, you can eventually expect it to climb as high as your house.
