Hummingbird Vine Won't Grow

I planted hummingbird vine 2 years ago, but it will not grow. The vine won't even try to climb the fence that's next to it. Can you give me some advice?

Melinda: Several plants go by the name hummingbird vine. The orange and yellow flowered trumpet vine (Campsis radicans) attaches to structures with aerial roots. The bright-orange, coral red or scarlet blooming honeysuckle vine (Lonicera) also attracts hummingbirds. It attaches to structures by twining around the support. Once you know which variety you have, make sure you give it the right support. A brick wall is good for trumpet vine, while a trellis or arbor is more suitable for the honeysuckle. You may need to provide a bit of guidance and support in the beginning. Secure the branches to the structure with twine or staking tape. Once the vine makes contact, it should continue to grow and cling to the structure on its own.
