Answer: Jan,
These are wonderful vines for attracting butterflies and hummingbirds (and nectar loving insects of all sorts), but you should be aware that they can be quite invasive in some gardens.
Trumpet Vines can be started from seed, suckers or by purchasing young plants. They will tolerate poor soil, but for the best show of flowers plant them in full sun in soil that is nutrient-rich and drains well. There really isn't much to growing them, with the exception of the need for constant pruning to keep them in check. They require moderate amounts of water and don't require any extra fertilizer to grow well.
The first two or three years of growth they will be putting all of their energy into getting established so don't expect to see any flowers. To keep growth in check, you can prune the vine in the late fall or early spring. Trumpet vines also send forth lots and lots of suckers. These can be managed with a shears (or a lawn mower), but don't dig them out or you'll end up with twice as many as you started with. Gathering seedpods before they pop and regular pruning will also help keep these vines in bounds and prevent them from taking over your garden.
You'll need to provide it with a sturdy support almost immediately after planting.
