If you want a wisteria, you should get a wisteria. There is a wisteria developed for zone 10 called the Blue Moon Wisteria. It's sold by Stark Brothers for $15.99 as of July 2017. (I discovered your post when I was trying to find one for my zone, also 10, in the foothills of southern California--rocky, sandy soil with ugly, hot weather and some cold snaps. Finally decided I would build the pergola first, but I have to find out if it has to be permitted. If it must be, I'll put in an informal cedar trellis instead. *ugh*) Keep in mind, the zone maps have to do with FREEZING temperatures. It's not carved in stone, and many plants that are NOT exposed to freezing (or non-freezing, as with the higher zones like 10, will be just fine--not like apples that need freeze hours. You need to know your plants (& area). If you're afraid that your plant will freeze, you can purchase gardening cloth to cover your plant in winter or while getting it started. The right kind will protect your plant from animals, certain amounts of freezing, and still ALLOWS water and sunlight through for very little $. (Short plants=cover gently and stake down.) Just don't use plastic (touching your plant). Think of your plastic wrapped fridge veggies--it lets cold right through. You can use a blanket or cotton sheet in emergency. Even a halogen lamp can save a small tree--just don't put the blanket/sheet over the lamp--hah!..fire! Be prepared. (Most folks won't go to the trouble of buying a can of anti-transpirant. [seals the plant from freezing for 3 months.] Also, some areas have their own personal weather because of land formations, building walls, even boulders, fences, & some plants or trees. Properly sheltered, plants can thrive. You could have perfect zone, but put a plant in dead soil (low microbes/fungi), under-water, over-water, etc., and it could die. The gov'mt is giving us an "odds" chart--does it include freak weather? I lived with small Passifloras in my dad's land around the farm. Never knew they grew as a big vine till this site. Loved them for their exotic beauty. All dad saw was "weeds." Sorry for the epistle, but Good luck y'all! P.S. Halfwaythere, for the cables you are considering using, there's a website that goes into rust, the breakaway strength & will lead you into stainless steel, coated, etc. (thecableconnection.com

I won't cut them back now. Control as well as you can this season. Prune heavily next winter and use good controls next yr starting early.

The first one needs more than a single flower, I think. Can you add leaf and vine and flower cluster photos? Trumpet vine is possible as is the related crossvine, I think, but see the link below to get more expert eyeballs on the problem. Second one definitely isn't poison ivy (I have lots of experience with it!), and actually looks more shrub-like than vine-like to me, but I have little expertise in southern plants. A great place to get plants IDed is on Garden Web's Name that Plant forum, which gets more traffic than this forum.

"Gold vine" = Hibbertia scandens, I assume. Both are great. In hot dry locations, passionflower vines can get a little dried out in the height of the summer though. Both need a decent amount of water to keep them lush and green in this climate. I wish more people in the area would plant more of these two. They're lush looking and beautiful, but not as drought-tolerant (i.e. "low-maintenance") as other common shrubs around here. The vines of passionflower are not as sturdy and will need something to climb on. Golden guinea vine is a bit more substantial, and it's growth habit is halfway between a vine and a bush, but it is not as fast growing as passionflower. Neither of the two behave invasively in this climate (warning to any of those thinking about planting wisteria).
