It is a truth universally acknowledged that Zooey Deschanel has had something of an iron-grip on our hearts ever since she starred in (500) Days of Summer. So, when she shared a recent snapshot into her home, it's little wonder that many of us sat up and paid attention.

I know, I know; at first glance, it's Zooey's cat (and rather fabulous cat tree) that steal the show in the Instagram photo. But look beyond the window? Why, then you'll find that there's another detail worth noticing: a tall black trellis, partly hidden by greenery, that adds a lovely vertical element to the terrace.

It's the sort of garden feature that's easy to overlook, but I think it's a particularly clever addition to a space that's viewed from indoors. Rather than simply providing support for a climbing plant, this particular type of trellis creates a focal point outside the window, giving the eye something interesting to land on beyond the glass.

Zooey Deschanel's Black Trellis

The benefits to Zooey Deschanel's black trellis (very similar in style to this trellis obelisk from Amazon) aren't purely aesthetic, either; as the climber grows, it creates a little more privacy, softens the view from the window, and provides some welcome shade from strong summer sunshine.

Better still? For those of us with distinctly smaller gardens or terraces than a celebrity, a well-placed trellis can make an outdoor space feel greener and more enclosed... all without taking up the floor space that a hedge would require.

It's an approach that seems particularly fitting for Zooey Deschanel. When she and Jonathan Scott opened up about their home to Architectural Digest, the New Girl star explained that they wanted their terraces to capture the cottage garden feel they love about their Los Angeles garden, and noted that they incorporated “a lot of trellis” into the design.

Now, a trellis is often treated as a purely practical garden accessory: put it against a wall, give a climber something to cling to and let nature take over, right? Wrong! Because positioning one where it can be seen from a window changes its role, allowing it to become part of the garden's architecture. The dark framework provides structure, while foliage and flowers gradually soften its lines.

Viewed from inside, that can create the impression of a much greener outlook (without requiring any major landscaping!). And this could be particularly useful on a terrace or small patio, where there may not be room for mature trees or a traditional hedge.

You don't need to find an exact match for Zooey Deschanel's trellis. Instead, look for a tall black metal obelisk (like this 100% Metal Garden Obelisk Trellis from LeJoy Garden) or open-frame trellis with enough height to create a noticeable feature from the window. (Honestly, using something like Amazon's Spiral Frame Trellis for Climbing Plants in a pot would do the trick).

The key is positioning. If your main reason for installing one is to improve the view from inside, don't automatically put it at the back of the border. Think about where you'll see it most often, and consider placing it where the framework and foliage will sit naturally within the sightline of a window.

Then, choose a climber suited to the conditions; clematis, climbing roses, honeysuckle and jasmine can all provide an attractive leafy screen, while sweet peas offer a faster-growing seasonal option.

Sometimes the best garden ideas are the ones that improve what you see from inside the house, and Zooey Deschanel's trellis is a brilliant reminder that a climbing plant doesn't just need something to grow on – the support itself can become part of the view.

And just like that, I'm off to buy myself a trellis. Race you to the checkouts!
