Over the last several months I’ve been discussing the Design Principle of Unity and how it can be incorporated into our landscapes and gardens. We’ve looked at Unity by Repetition, Unity by Dominance and Unity of Three. Today I wrap up this discussion with a look at one last way we can create unity in our gardens, with the use of Interconnection.

Interconnection refers to the practice of connecting or physically joining all landscape elements and spaces. Now you’d think that since the definition of Unity is oneness, that the idea of interconnection or joining would be a no-brainer, but I have trouble convincing gardeners of this one. It’s certainly harder to achieve if the basic layout of your landscape is already in place, especially the hardscapes (patios, walkways, etc.), but if you have the opportunity to physically connect all your landscape spaces, the result is very pleasing. So what do I mean by this? Let’s look at the example below. In the image on the left, a number of different landscape features – a deck with a hot-tub, patio with a fire-pit, and kidney-shaped island beds – are all floating disconnected in a sea of lawn. This composition lacks interconnection. The image on the right includes the same landscape features but the spaces are now all linked together, hence this landscape has been unified through interconnection.

Left: landscape lacks unity. Right: landscape is unified through interconnection. Note how the lawn in the composition on the left, is ‘negative’ space, i.e. the space between the landscape elements. In the image on the right, the lawn has become a landscape element and the planting space is now the negative space.

What this means fellow gardeners, is – brace yourselves – no island beds. I suspect therein lies the gardener’s grievance with interconnection – we do love our island beds don’t we? But think about it, the word ‘island’ by definition means disconnected. Just to be clear though, this rule doesn’t apply to acreages where very large island plantings are often employed as spatial definers – perhaps to separate the landscaped area around the house, from the ‘back forty’.  In this case the plantings are large enough that the eye doesn’t experience them as islands, so unity isn’t compromised. Neither would it apply to botanical gardens, or show gardens – again the plantings are too large to be seen as island beds, and are planned in such a way as to facilitate foot traffic for maximum viewing potential.

Interconnection can also be utilized to unify an individual planting space – disparate groupings of trees, shrubs and perennials can be underplanted with a single type of groundcover or other low growing plant. This connecting plant material brings the dissimilar groups into relationship with each other, therefore unifying the whole planting composition.

The idea of Interconnection is really underscored for me when I look at the evolution of my own garden. When we purchased our house almost 25 years ago, the only growing things in the front yard were two Cotoneaster shrubs, which the previous owner had tried in vain to kill, and a green ash tree, all of which were on city property. The only garden beds were small strips of soil against the foundation:

Over the next few years, I built upon these beds, first expanding the beds adjacent to the house and carving out a kidney-shaped bed around the ash tree:

A year or so later I decided to make the bed in front of the house a little curvier and I added a couple more island beds:

I kept adding and expanding until eventually it looked something like this:

I was never really happy with the design as a whole, even though each individual bed was nicely planted. When I’d stand back and try to take the whole thing in, what I saw was a bunch of scattered puzzle pieces – a disjointed picture, as if the puzzle was yet to be assembled. It wasn’t until I became a student of design that I discovered what the problem was; none of the beds were linked or touching, hence no interconnection = disunity. A number of years ago I decided to correct this and proceeded to join all of the beds.

It’s an improvement to be sure, but there are still flaws – a couple of acute angles which as you know is a design no-no. As well, due to the positioning of the sidewalk, the two sides are still unbalanced – but that’s a whole other story. In fact it’s a whole other design principle, that being the Principle of Balance which we’ll look at next month. Stay tuned.
