New to this forum. I don’t know where my paragraph and formatting went! Apologies for the jumbled read!

There are some evergreen vines that could work for you. However, they are unlikely to fill in in a single season. You may need to supplement with annual vines for a couple of growing seasons.

Possibilities: (these may be borderline hardy in your location and also might not be fully evergreen)

• Clematis armandii
• Passiflora caerulea
• Trachelospermum jasminoides
• Akebia quinata

I'd like to address not the plant choice, but the trellis. I honestly don't think that stakes and netting will hold up to a vigorous climber, even for one season. Even Scarlet Runner Beans or Morning Glory need a very sturdy frame if they are not going to blow down in windy and or wet conditions. The whole thing could be a sagging floppy mess by the end of summer. I would spend a little more and get a good quality, robust trellis which, even unclothed, will form a visual barrier. All GG's suggestions would not work on stakes and netting. They need something solid and permanent.

Tysm GardenGal & Floral_UK for your replies.

I had not thought of annuals to fill in in the interim. Great idea!

And I figured someone would mention my trellis hack. Lol. I did this successfully in a previous house with passion fruit (that actually fruited in 7b!). What a glorious fast growing beauty! That being said, that was about 12 feet in length and in our new home I’m looking at about 30.

My reasoning is partly cost, yes. We already put in quite a bit of $ last year totally gutting and redoing the back. But primarily bc of HOA rules about fencing height. I can’t lengthen the existing fence or add to it with screens. And I don’t want to cut off my yard with large structures placed away from the perimeter. We tore down 2 dilapidated ones when we moved in last summer. Besides the condition, they also made the yard look and feel about a quarter of its actual size. But I do see why the previous owners had them there!

If my invisible under the hoa-radar trellis hack won’t bare the weight, what else might I do?

A perennial vine that can fill in in one season can overfill in the next unless you upkeep every season to have one season fill. Slower filling vines like gardengal suggested will take longer, but also be easier to control the fill and upkeep on them. But if you can't have trellises tall enough to suit you that are also sturdy enough to suit the vines, you might need to consider other options.

How high is your fencing height allowance? How much higher than that do you feel you need screened? What are you allowed for plant support structures? Are you allowed other structures like arbors or pergola walkways? What kinds of planting are you allowed- can you perhaps use tall slender bushes or controlable shrubby trees?

Fencing height permitted is 6 ft and the existing fence is 6 ft. Problem is the house behind and on the left are a bit elevated above us & so their decks are above the fence line. I figure I need to go like another 6 feet up to get good enough coverage so that I can sit on my patio in peace and be surrounded by flora, not houses.

We did immediately plant a row of thuja green, which I’m regretting a bit because maybe there’s a hedge that would have been a better choice. I wish I hadn’t been so hasty. I’m looking at probably 5 years before they give me anywhere close to the coverage I need.

So where am I now is trying to figure out a solution that will work until the trees fill in years from now.

I don’t think there is any rule around what I place IN my yard if not on the fence line. And we had those two huge wooden privacy walls prob about 13-15 Ft high when we moved in. But they chopped up the yard and made it seem so small. I hesitantly had them pulled out as part of the total project redoing the back.

It might make more sense to go with a barrier while waiting for your hedge to grow in. Solar sail thing? Clothesline covered with sheets? :)

A fast growing evergreen vine is bad news.

Have you considered a lattice screen (Vine covered or not) beside your patio rather than along the fence line?

I’m glad I posted this bc you all are really giving me things to think about.

I’m hearing that a fast growing perennial is going to become an unruly beast. Is that accurate? Just don’t go there?

And my stake and netting hack will not hold the weight of any vine?

Ideally I don’t want trellis or screens IN the yard (like next to the patio) that make the yard look smaller. I’m thinking of the approx 15 ft structures that were there before. Or is there a less obtrusive approach?

The other option could be placing high screens maybe 1-2 ft away from the fence and cross my fingers that I get away with that. But these would need to be really tall. Like 13 ft at least. I can’t find anything larger than maybe 8 or 9ft when looking online for something I can buy. Would I have to have these custom made? And how pricey are we talking? See pic below. Something like this but really tall.
