Elements of Design: Mass in Landscape Design

There was a guy at one of the gyms at which I worked out who had a T-shirt that said “don’t be passive, be massive.” He was definitely the latter; you kind of have to be to pull off such a shirt.

Mass in the landscape is the same way – it has to be right if you’re going to pull it off. Mass is very closely related to shape and form. Actual density occurs when the shape is filled in. Optical density is when the piece in question is not completely solid. In terms of interior pieces (a common reference point), think of a couch that has a skirt all the way to the floor versus a couch of the same size with no skirt and tapered legs. The skirted couch appears to have more mass, even though it’s not solid all the way through.

How the heck does this relate to landscape design? It’s important to consider the effect that mass has on the pverall feel of a space. Obviously the bigger the space, the more mass it can handle. At the same time, it’s important to recognize that a heavy mass can “stop” the eye and make the space feel smaller.

This pergola is a good example of playing with mass. It’s a big site, and the large house is just out of frame – this needed to be a beefy structure. At the same time, the openings provide a little transparency and lighten things up a bit. You know it’s a focal point, but you can still see through it to the vineyard view beyond.

Plants can play a role in this as well. If we keep the plants behind the structure pruned even with the top of the fence, we’ve preserved the view to the vines and maintained a lighter mass. If we allow the plants to fill the space between the columns, it’ll have the same effect as if we had built a solid wood screen panel between them.

Because plants grow, you have to think about the effects of mass throughout the life of the landscape. It’s one more reason why working with a landscape designer can make a big difference in the overall look of your landscape.

6 Screening Plants That Aren’t Leyland Cypress

UPDATE! There’s a new post up on planting for privacy – be sure you check it out!

My name is Dave Marciniak and I hate Leyland Cypress. It’s unattractive before it fills out, it’s no prize once it does fill out, it gets way too big (30′ wide and 50-60’+ tall) for the suburban lots on which they’re planted, and bagworms consider them a tasty snack.

I’ll admit that Leylands are, in part, an easy target for my ire because they’re often used in a really boring manner. I get that you have an unattractive view you’re trying to screen, but lining up as many of a single plant as you can plop in the ground is just boring. Emerald Green Arborvitae is another plant used this way.

See? One more reason not to browse the web on your phone while driving – you might have just fallen asleep and wrecked your car, thanks to this photo.

It’s the same problem at any scale. Our friends over at a local winery wanted to put up an evergreen screen along an edge of their property that they may end up sharing with some new neighbors. Can’t say that I blame them. Who would want to give up a view like this?

Anyhow, a local nursery recommended throwing a row of White Pines across the property line. Yawn. You’re a nursery, do better! So I developed this plan for them:

Let’s look at each plant I used here:

1- Cryptomeria japonica ‘Yoshino’: I’ve talked about this one before, as it’s a favorite. With an eventual height of 30-40 feet and a spread of 12-20 feet, it’s a well-behaved tree that will hide a multitude of sins in the neighbor’s yard. It’s a quick grower, too.

2- Black Pine: A tougher pine than the common builder’s favorite, white pine, the black pine will easily grow to 20-30 feet or more, with a similar spread.

3- Deodar Cedar: Bluish-green foliage and a height of around 50 feet make this tree an interesting specimen to mix into an evergreen screen.

4- American Arborvitae: this is a great choice for narrow locations too. Overall height ends up around 25-40 feet, with a spread of 10-15 feet.

5- Kwanzan Cherry: Now wait, you say, this isn’t an evergreen! And that’s true. Part of eliminating a problem view is blocking it; but another component is misdirection. When these trees get covered in their gorgeous pink blooms in springtime, no one’s going to be looking at what’s beyond.

6- Maple: We actually used a Commemoration Sugar Maple, which gets a great blaze orange color in the fall. At 50 feet tall and 40 feet wide, this will be another great foreground tree throughout most of the year. These and the cherries allowed us to create a layered planting, which makes it look more like a farm windbreak and less like a suburban “hide the neighbors” screen.

The bottom line is that just because you have something you want to hide from view doesn’t mean that the best way to do it is with a single, straight soldier row of the same boring plant. Play with texture, play with color, and use some tricks that not only block the view but give the eye a reason to look somewhere else.

Green Giant Arborvitae are another great alternative to Leyland trash trees!
