The Form of Things to Come

My first thought the morning of February 2nd is hooray! Balzac Billy didn’t see his shadow! According to groundhog legend, this means spring is just around the corner. Again I say hooray! A sense of disquiet ensues though, as I remember the client designs I’ve been putting off because hey, there’s lots of time, it’s still the middle of winter. While I don’t really subscribe to the belief that a rodent can predict the weather, I suddenly feel called out of hibernation. I’m not sure I’m ready.

I dust off the old creativity cap and reluctantly put it on. I’m just not feelin’ it though. I guess I could work on my next blog post – yikes not feelin’ that either. I believe I have the dreaded writer’s block, and designer’s block too! This is weird – my brain is usually so full of thoughts and words and ideas that stuff just tumbles out onto my drawing page or laptop screen.

A memory of some words my husband once spoke to me finds its way through the fog, “Sue, just put your pencil on the paper and start to draw”. Yes, yes of course – start the process and inspiration will follow. I know this to be true.

Fortunately I’m able to come up with some concepts for last night’s client meeting – I’m actually pretty happy with the drawings, and the clients are ecstatic. Now if I can just get this blog post underway. So where were we anyways? Oh yeah, in my last post I left off with the promise of discussion on the significance of plant form, texture and colour.

Plant Form

We choose plants for any or all of these characteristics (form, texture and/or colour), but in order to arrange them appropriately we need to understand how specific traits will play out in the garden scenario, in relation to other plants. To me, plant form is the most important quality a plant brings to a garden composition, so I’ll begin there. It is the various plant forms working in concert that creates a sight-line. Much like a city skyline, the landscape sight-line is what we experience when viewing the garden from more distant vantage points – across the street or down the road. It allows us to see the garden in its larger essence.

As well, the form of the garden’s woody denizens (trees and shrubs) makes a significant contribution to the creation of a true four-season garden. It is this that provides a sense of permanence in the garden – to see its beauty season after season, year after year.

Plants come in many shapes. Classifying these shapes, simplistic though it is, can help us to understand their visual impact in the landscape and utilize them accordingly. For the sake of simplicity then, let’s say plant forms fit into one of the following categories:

  • Columnar/Fastigiate
  • Pyramidal/Conical
  • Vase shaped
  • Weeping
  • Topiary/Grafted standards
  • Fountain/Arching
  • Round/Mound
  • Mat/Flat

Today I will discuss the first.

Columnar/ Fastigiate

Columnar and Fastigiate forms are tall and narrow with very little taper. These strong vertical accents draw the eye, stop it, and send it skyward, thus momentarily arresting the flow of movement. Stately and spire-like, they have many applications in the urban landscape.

When used as a single specimen, a columnar form appears somewhat like an exclamation point. They are also lovely as a trio, and placing one on either side of an entrance or view will provide a visual frame, inviting the eye (or the viewer) through.

Columnar forms are useful where taller scale is required but space is tight. As well, adding a few of these tall narrow trees to Mediterranean theme gardens can help to set the mood as they mimic the tall Italian cypress.

Nothing says Mediterranean quite like Italian cypress – it is seen in abundance throughout the region. In colder climates, like ours, other columnar trees can do the trick quite nicely. Photo: Cathy Gaviller

Overuse of this form can result in very choppy movement as the eye stops and starts, darting up and down. This ‘jumpy’ feel will be most evident if these forms are dotted randomly around the landscape. If you want to use numerous columnar forms, they are best grouped together, used sequentially to reinforce a design line, or in a pattern of alternating elements.

On a smaller scale, columnar form is seen in these Calamagrostis acutiflora 'Avalanche'. They provide winter interest in both form and colour. Photo: Sue Gaviller

The columnar plant form is an outstanding addition to the landscape – why not give one or two a home in your garden.
