You may do better with a clinging vine. I especially like Parthenocissus quinquefolia 'Star Showers'; variegated Virginia creeper. You'll need a good sized container or tub.

Please know that the berries produced by this vine are poisonous: https://plants.ces.ncsu.edu/plants/all/parthenocissus-quinquefolia/

That is not all that much sun. Common choices like Clematis, and jasmines might want more sun. Then too, some vines are sooooo...., "vigorous" shall we say, they quickly overwhelm a smaller area. My current vine list is currently limited to American wisteria (but they want more sun). (I used to grow here, in New Jersey, Chinese Kiwi and grapes, but they grew so luxuriantly and aggressively that I had to cut them out completely once they invaded the neighbors yard.

What about climbing Hydrangea. They seem to be really underused, are shade tolerant and quite attractive. I wish I could grow them where I am but my deer LOVE Hydrangea to death! LOL! There is also Pyracantha coccinea (which is an evergreen with red berries in the winter, but not sure of your hardiness zone (I think they are good to zone 6b/7 climates in NJ).

I'm not sure a perennial would survive in a pot in your zone..has anyone tried it?..my neighbor had some shrubs (boxwoods) in pots and they died..I loved the idea but after that didn't try it..

Perennials and shrubs supposedly will survive winter in a container if they are winter hardy two zones colder than the zone in which they are planted. So, central Jersey being 7, anything hardy in 5 should be OK. I think one of the challenges here are the extreme temperature fluctuations, alternately warming then re-freezing the growing medium. A planter that provides some insulation should help.

I love climbing hydrangea, finally got one years ago, but they get *monstrous* - able to cover the side of a two-story building. I don't know ... yet ... how well they take to pruning to maintain their size, but will soon have to find out.

A really suitable vining plant, or one that could be secured to that trellis, just isn't coming to mind right now. Will keep it in mind.

Thanks, everyone. I have kids and a dog, so need to stay away from the poisonous variety. LOL. I love the thought of climbing hydrangea although I'm worried about it making it through the winter in a container. Someone also mentioned black-eyed susan vine or morning glory to me. I'm leaning toward an annual. Are climbing plants readily available at nurseries?

If you want an annual, there is always passionflower, stunning flower btw (a few species of which are actually ground hardy in zone 7...., in the ground).

I am at jersey shore. I think morning glory is a good choice for starters as you will enjoy flowers in a few months. And you can collect the seeds for next year. Honeysuckle is also good perennial as it is a native plant. Or sweet peas will give you fragrance as well. I also think hyacinth beans will be pretty again your lattice too.

A perfect blank canvas! Not sure about climbing hydrangea in pots and they will need stronger support than offered by this trellis in a few years. Passion Vine is a good annual choice for the amount of sun this area will receive. Morning glories also will do well with limited sunlight, but self seed like crazy. Moonflower is similar, a larger white blossom that opens in the evening. Major Wheeler Honeysuckle is a native and much loved nectar source for hummingbirds. Also, love the suggestion for hyacinth beans as the burgundy leaf color would look stunning against the wood lattice. It is an annual, but the seeds can easily be harvested and saved for next year. Good luck. Please, post a photo of your choice in bloom.

Climbing hydrangea would do very well in morning sun/afternoon shade, and is probably hardy enough to survive in a container until it outgrows it. I even have a branch that rooted itself that I could cut off and give to you ... However ... it would completely overtake that trellis in a few years, as they will easily grow to cover the side of a two-story building.

If you decide to go with morning glory, perhaps plant both morning glory and moonflower, as they m.g. will give you flowers in the daytime, and the moonflower will bloom in the late afternoon-evening, when the m.g. flowers have closed.

Mina lobata "Firecracker vine"always did well for me. Very showy annual vine.

I'd say avoid morning glories, as once planted you will never be rid of them. I'd suggest planting maybe 5 or 6 moonflower seeds. They grow very fast and are aggressive, so let them grow up the trellis and cut any vines that come out horizontally onto your patio. Very big leaves and huge, showy flowers from evening to midmorning. They are annuals, so collect the seeds in fall or try to let it reseed itself if you like it.
