You could do morning glories, hyacinth bean vine or even red cascade rose. None of those got out of hand for me.

Is unfortunate that the best long/repeat blooming vines seem to also often be among the most aggressive. Coral honeysuckle seems like a great alternative - very pretty this time of year and does repeat a bit for us throughout the growing season. Also appreciate the somewhat different look it gets throughout the year being semi-evergeen in north Texas.

Crossvine and Carolina Jessamine are native evergreen spring bloomers that behave themselves around our neighborhood. All parts of jessamine are toxic, which rules it out for some folks/locations. We've not had problems with crossvine spreading, but it does try to use all its space; could become a lot of vine for your narrow arbor in 5 or 6 years.

Some clemantis varieties are good possibilities not always considered in Texas. We coddled our big box 'Jackmanii' vine for years, and it hated us for it. Divided and moved the roots when the tree it had been growing on was taken down. Found it is MUCH happier in full sun living off the weekly (when needed) lawn watering. The newer native hybrids are also nice (and tough), though don't have the large flowers. Slower covering than others since can take a couple years to get established.

Another vote for hyacinth bean vine though it has gotten aggressive for me. The nice thing about an annual is that you have a few months when it is not growing to check for and remove any trumpet vine starts. I did the same as you and planted trumpet vine on purpose. I had to constantly keep it in check where I planted it and then would find it popping up on the other side of the concrete pad. Then, one year, it just died. I have no idea why but I was glad. I still fought it for a few years where it popped up in other places.

Thanks, all! I've had Hyacinth Bean before and loved it. I have a Sweet Autumn Clematis on a trellis, and love it, too. The Coral Honeysuckle I had at my old house was awesome. Hmm, decisions! :)

Sweet Autumn Clematis is nice, but I've always been cautious (ok... afraid) of it for the aggressive/invasive reputation it has in some places. If already works for you, the new (2014?) 'Sweet Summer Love' hybrid might be worth a look. Late summer blooming cranberry/purple flowers while supposedly less agressive than the straight SAC.

Thanks, bostedo, I'll look for that one (I have another spot I want to put a trellis). I love purple flowers.

I've been lucky with my SAC, I know. It's been very well-behaved, thank goodness. I cut it to the ground every winter.

It has tried to choke out a nearby Nandina, but is easy to pull away. The Nandina holds its own. :D

Oh, wow, bostedo, I'm in love! The SSL vine is stunning!

I just googled it:

Gorgeous, wantonamara!
