Chris, you are so very welcome!* I wouldn't recommend wisteria unless you are going to build a VERY sturdy arbor with 4X4's or 6x6's.* Wisteria will take some time to establish their roots and could take up to 5 to 7 years before it blooms.* The two biggest problems with wisteria, and that's no pun, is it will need pruning 3 to 4 times a year once it gets going and will get heavy enough to bring down a less then VERY sturdy structure.* Both the Chinese and Japanese wisteria are also invasive in many areas.
As for annual vines, I would stay away from morning glory.* Once you plant it you almost always have it.* The seeds can remain viable in the soil for years.* We renovated our garden 4 years ago.* We had to remove much of the soil to regrade.* All the morning glory was removed and I'm still getting sprouts from dormant seeds.
Hyacinth bean is an old-fashioned vine, making a big comeback. Hyacinth bean, Dolichos lablab, is a fast growing member of the pea family with large purplish tinted leaves with dark purple stems. If this weren't attractive enough, by mid-summer it is covered in deep lavender pea-like flowers. These long lasting blooms, are then transformed into glossy purple four inch seedpods, which are every bit as pretty as the blooms. It will grow up to 15 feet in a season. Uncooked beans and flowers are poisonous. Full sun to partial shade.
The Scarlet runner bean, Phaseolus coccineus produces large vines with attractive scarlet flowers that also attract hummingbirds. You can eat the flowers, pods and seeds of this versatile bean.
Another old-fashioned annual vine is the black-eyed Susan vine or clock vine, Thunbergia alata. Flowers may be orange, yellow or white, with or without a black center or "eye". The common name clock vine comes from the fact that the vine will twist around its support in a clockwise motion. These vines can be grown in a hanging basket, or it can climb a trellis, six to eight feet in a season. Partial shade is best, and this is not a drought tolerant plant, so be prepared to water.
Asarina, commonly called creeping gloxinia, is a member of the snapdragon family. This vine is native to Mexico where it reaches great heights. It should grow at least ten feet tall, and blooms best in the sun. Flower color varies from shades of pink to purple.
Cobaea scandens, or the Cup and Saucer Vine produces interesting flowers that start out as green papery buds and open to reveal the green saucer and bell-shaped flowers. They start off white, changing to deep purple before falling off. This sun-lover can grow twenty feet or more.

When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
