ELEMENTS AND PRINCIPLES OF LANDSCAPE DESIGN

*Underlined words are defined in the Glossary of Terms.

Design is as individualistic as the person

who designs. However, the elements

and principles of design are means

through which a designer monitors the

effectiveness and success of a project.

These elements and principles serve as

structures and guidelines for design

development. The design elements are

the tools a designer uses to accomplish

the design principles in a project. Noconsensus exists within the design world

on the finite list of elements and

principles. Definitions and understanding

differ from one person to another.

The elements of design are line, form,

texture, and color. A designer uses these

elements to generate a design. The

principles of design are focalization, proportion and scale, balance, order and unity, repetition, rhythm and sequence,

and interconnection. Use the elements of design to accomplish these design principles.

Most artists incorporate the principles of design into their projects. However, some artists break the principles.

Experienced artists who break the principles with solid intentions are usually successful. These artists use line,

form, texture, and color to complete a composition*. However, the artists may or may not incorporate all the

principles of design into the composition.

Landscape designers are artists. The same elements and principles of design found in works of art also apply to

landscape design. These elements and principles of design make up the art and science of landscape design.

ELEMENTS OF DESIGN

The elements of design are the visual and physical features of the plant and hardscape components that make up a

landscape design. These features include line, form, texture, and color. A landscape designer uses these features to

enhance the design principles.

Line

Line plays an important role in a landscape. This design

element causes physical and/or visual movement. Line

leads the viewers eyes through the landscaped space.

It defines and delineates space. A skilled designer

recognizes the use of line. He/she applies line in all aspects

of the landscape.

As a designer, incorporate line into a landscape by using

contrasting plant material and by forming patterns with

similar plant materials. Pattern is line organized in a

repetitive sequence. Examples of lines created in a

landscape include ground patterns, edges of contrasting

plant materials, and tree tops meeting the sky.

Steer physical or visual movement directly through the environment. Use straight lines to represent formality or a

contemporary concept. Intersecting straight lines suggest hesitation, change of view or direction, or a pause.

Meandering or curved lines suggest a more relaxed, slower movement. Use these to create a casual, informal concept.

Form

Form is the two or three-dimensional shape and structure of an object or space. Whether it is two or three

dimensional, form is line surrounding mass. The shapes of trees and the areas of grass bound by edging are

examples of form expressed in a landscape. The air space created by two plant materials set side by side is also an

expression of form.

All the components in a landscape have a distinctive and natural form. The forms of plants contribute to the total

design composition. The basic form of each plant depends on the plants natural growth habit. Some of the more

common forms of landscape plants include round, conical, oval, weeping, horizontal, and upright.

Most deciduous trees and shrubs have a rounded form. A conical form is characteristic of many evergreen trees.

Evergreen shrubs have more of a horizontal form.

The concept or theme for a landscape dictates which forms are most appropriate within that concept or theme.

Formal concepts suggest the use of very tailored forms of plant material and ground beds. Such a formal landscape

would include very straight, crisp, and precise planting beds; topiaries; and other visually clean-lined plants. Informal

or woodland concepts mandate much more irregular or natural forms. Casual curving ground beds and loosely

branched trees and vines have forms to satisfy this concept.

As a designer, incorporate form into a landscape to manipulate a persons emotions. Use vertical forms for strong

accents and for adding height. Horizontal or spreading forms add visual width to tall structures. Incorporate

weeping or drooping forms to create soft lines and to provide a transition to the ground plane. Rounded plant forms

create large masses and are effective as borders and enclosures.

Consider the element of form when making design decisions regarding design details for plants, structures, and

ground patterns.

Texture

Texture is the surface quality of any plant material or structure in the landscape. It is the feature of a plant or

structures physical surface qualities as determined by form and size. Texture is also a feature of the aggregation of

the minor units that make up the plant or structure.

Texture is relative. It must be seen as a comparison. Texture is analyzed by comparison between objects, by

association of these objects with each other, and by distance.

Texture is associated with the senses of touch and sight. Referring to the physical surface of plants (smooth, rough,

shiny, or dull), texture is tactile. Texture is also viewed as the organization of the size and arrangement of a plants

component parts (leaves, stems, and branches).

In addition to being a physical feeling like rough or soft, texture also describes how one perceives a visual difference.

For example, the leaves of one plant are rough and coarse when compared to the smaller leaves of a second plant.

However, when compared to the larger leaves of a third plant, the smaller leaves of the first plant appear smooth

and fine. As another example, consider coarse-grade pea gravel. Next to fine sand, the pea gravel has a coarse

texture. When compared to granite or marble chips, the coarse-grade pea gravel has a finer texture.

Visually coarse textures have border impacts. Coarse textures keep the viewers eyes busy. Progressing from fine

textured plant material to coarse textured plant material in a landscape tends to contract the composition. The coarse

textured plant materials appear to advance toward the viewer, making a large space seem smaller and more intimate.

Finer textures are easier for the viewers eyes to span. With finer textures, the eyes continue searching for an

accent on which to focus. Progressing from coarse textured plant material to fine textured plant material in a

landscape tends to expand the composition. Fine textured plant materials visually recede and appear farther away.

They make an area seem larger and more expanded.

Texture gives a designer an added dimension for providing greater variety and interest to a landscape. As a

designer, proceed with texture changes in a logical and graduated manner. Proceed in sequence so the continuity

of the landscape is not disrupted.

ACTIVITY: Acquire several specimens of landscape plants. Compare their textures in relation to each other.

How does the texture of each specimen change when compared to the texture of each of the other specimens?

Color

Light is the source of color. Light consists of several visible wavelengths. Each wavelength produces a characteristic

color. Color and light are inseparable. Without light, color does not exist. White is the accumulation of all light.

Black is the absence of light.

The colors that people see are reflected wavelengths. For example, the color perceived as red is the red wavelength

reflected from an object. This reflected wavelength is received by the eyes and perceived in the brain. The other

visible wavelengths are absorbed by the object and not received by the eyes.

Artists and designers use the color wheel to study colors and their relationships. A position for all colors exists on

the color wheel. Red, blue, and yellow are referred to as the primary colors. These colors cannot be made from

any other color.

Combining any two of the primary colors produces a secondary color. The secondary colors are violet, green,

and orange. Mixing red with blue makes violet. Blue mixed with yellow creates green. Mix yellow with red to

get orange.

red + blue = violet

blue + yellow = green

yellow + red = orange

The primary and secondary colors make up the color spectrum. The color spectrum can be seen when visiblelight passes through a prism. The prism separates, or refracts, the light into the individual colors making up the

color spectrum.

Combining equal parts of a primary color and an adjacent secondary color produces a tertiary color. The name of

a tertiary color consists of the names of both colors from which it was created. The primary color is always named

first. For example, red mixed with orange creates red-orange. Six tertiary colors exist on the color wheel. These

colors are red-orange, yellow-orange, yellow-green, blue-green, blue-violet, and red-violet.

White, gray, or black added to any of the twelve

pure colors (hues), respectively produce a tint

(pastel), tone, or shade of the color. White, gray,

and black are neutral colors. Value describes the

lightness or darkness of a hue. A pure hue has full

value or intensity. Decrease value by adding white to

make a tint. Increase the value by adding black,

which creates a shade. Adding gray makes a tone of

any hue.

Using color in a landscape is the same as with any other form of art. Knowing the effects of color is important

to the designer when contemplating the landscape design. Designers use color in the landscape as a background

or basic gentle wash to harmonize the view onto the landscape. Colors used in this manner are pleasing and

smooth. Another use of color in the landscape is for accent. In this manner, color is an emphasizing factor for

the composition.

Color combinations incorporated in a design influence the moods of those who interact with the design. Bright

colors excite or stimulate emotional responses. Subdued or cool colors slow down emotional responses andexpress a sense of restfulness.

Yellows, reds, and oranges are warm and advancing colors. These colors are associated with warmth because

they are the colors of the sun, fire, and heat. Warm colors add a dramatic and excited feeling to an environment.

These colors appear to advance and move toward the viewer. Warm colors can infuse a high energy level into

those with whom they have contact. Objects or plants with these colors stand out and are the first to be seen.

The cool colors of blue and green express restfulness and coolness. These colors are associated with ice, sky, and

water. Cool colors have a receding visual effect. These colors provide the viewer with a sense of depth. Cool

colors make the object of interest appear to be receding into the background.

Warm, yellow sunlight and cool, blue moonlight have very different effects on color in the landscape. Artificial

lighting also has a dramatic impact on color.

As a designer, consider several factors concerning the influences of color in a landscape design.

1. People have a psychological tendency to lean toward light and vivid colors.

2. Bright light and warm colors excite emotional responses. These conditions encourage the viewers eyes to

move throughout the landscape.

3. Subdued light and cool colors are more conducive to moody reflections of thought.

4. Warm colors (red, yellow, orange) appear nearer or advanced. Cool colors (blue, green) appear receded or

farther away.5. Plants or plant masses must blend with their surroundings. If a color change is desired in a plant mass,

proceed in a sequence. A gradual color change in the plant mass maintains the continuity in the design.

6. Colors and textures relate. Delicate colors (tints and pastels) express fine textures. Earth-tone colors

(brown, rust, red) express coarse textures.

ACTIVITY: Research and identify the different types of light bulbs available for lighting purposes. Observe the

light spectrum of several of the examples. Perform an experiment on the effects the different types of lights have on

the color of plants. Which lights would be most appropriate for use in the landscape?

PRINCIPLES OF DESIGN

The principles of design serve as guidelines that

govern the organization of the design elements and

materials in accordance with the laws of nature.

Landscape design principles include focalization,

proportion and scale, balance, order and unity,

repetition, rhythm and sequence, and

interconnection. Landscape designers use these

principles of design to create landscape designs that

are both functional and aesthetically pleasing.

Focalization

Focalization is created as a visual break in the sequence and flow of the landscape. The focal point is the point or

area of the landscape that attracts the viewers eyes. The visual break captures the attention of the viewer and

draws it to the focal point. Without a point or area on which to focus, the viewers eyes become lost and confused

throughout the landscape.

As a designer, create an accent or focal point that is strong and effective. Do not incorporate too many focal points

into the landscape. Otherwise, their effect will be lost. Use the design elements (line, form, texture, and color) to

move the viewers eyes through the landscape to the place of the focal point.

In addition to using the design elements to create and draw attention to a focal point, incorporate similar plant forms of

varying sizes. Create a focal point with a contrast in spacing between the plants or by grouping several plants together.

Most landscapes usually contain visual focal points such as plants and structures. However, running water and

rustling leaves are effective as focal points, capturing the sense of sound.

The focal points in a landscape may also be focal areas. These focal areas may change throughout the year. For

example, the trees with their changing foliage are the focal area during the autumn. In the spring and summer the

focal area changes between colorful groups of annual bedding plants and groups of blooming trees and shrubs in

the landscape.

The focal area attracts the viewers eyes in the same manner as the focal point. However, the focal area consists

of more than a single element or component. Focal areas consist of a group of parts or components.

Minor focal points are effective in advancing the viewers eyes through the landscape to the main attraction or

dominant focal point. When incorporating minor focal points into a design, take caution so as not to confuse theviewer. Keep the minor focal points minor, compared to the dominant or major focal point.

If color is the element to be used as the focal point on a site with great depth, use blues or whites as minor focal

points. Advance these minor focal points to a dominant red, orange, or strong yellow focal point. Why advance

with this color sequence? Remember that warm, bright colors advance toward the viewer and cool, subdued

colors recede from the viewer. In this color sequence, the viewers eyes move from blue to blue until they focus on

the red.

Proportion and Scale

Proportion is the relationship that exists among the components of a landscape. It also describes the relationship

between the components of the landscape and the landscape as a whole. Proportion involves the size relationships

between and among the components making up the landscape.

Proportion describes the mathematical relationships among the dimensions of space and site components making

up an area. These mathematical relationships are totally separate from human perception dimensions. In a sense,

proportion is similar to a ratio. For example, corner plantings next to a house that are two-thirds the distance from

the ground to the eave are proportional to the house. The height of the corner plantings is proportional to the height

of the eave.

Scale is the human perception of the size of space and form related to the human dimension. Scale is relative to the

perception of the viewer. For a large two-story house, corner plantings that are proportional to the house may

appear out of scale to the viewer.

Because scale is relative to perception, a designer can manipulate scale psychologically within the site. Although

the components of the site may remain proportional, a change in the placing of the components will dramaticallyaffect the scale.

Plan for trees in settings relative to the size of the matured trees. Plant tall trees near a tall, narrow house or

building. A small house surrounded by large trees appears smaller than it actually is. A large house surrounded by

small trees appears larger than it actually is.

A design is in proper proportion and scale when a pleasing relationship exists among and between each component

and the design as a whole.

Balance

Balance is a design principle defined in terms of weight.

It is the equalization of visual weight from one area of a

landscape composition to another. Two distinctly different

types of balance exist in landscape design: symmetrical

and asymmetrical.

Symmetrical balance is a formal balance. It is sometimes

referred to as bi-lateral symmetry. Symmetrical balance

is recognizable in that an exact sameness occurs on either

side of the composition. The same components are

repeated on both sides of the composition. If a line (center

axis) were drawn through the middle of the form or space,

each side would be identical. The visual and actual weight

is equally distributed on each side.

A symmetrically balanced landscape compares to a level balance scale. Both sides of the scale are level with theexact same weights on each plate.

Asymmetrical balance is an informal balance. It does not repeat the same plant material in the same quantity or in

the same relative position on either side of the center axis. An asymmetrically balanced design implies equal

weights on either side of the center axis. However, it does not have the sameness on each side.

An asymmetrically balanced landscape compares to a level

candy scale. A quantity of candy is balanced by weight

similar to the weight of the candy. Although the objects

are different on either side of the candy scale, the scale is

still balanced because the weights are equal.

While viewing an asymmetrically balanced landscape, the

viewer feels a sense of stability. If one side of a landscape

does not equally offset the other, an imbalance results.

Such an imbalance is similar to an unbalanced scale.

Imbalance in a landscape is not desirable.

Order And Unity

Order and unity are emotional and visual reactions to the overall structure and organization of the design elements.The designer blends the design elements and the design detail decisions of materials with the existing site conditions

to establish order and unity. The concept created by order and unity is carried out throughout the design.

Order is the overall organization and structure of a design. It is the basic scheme or skeleton of the design.

Order is created and carried out through the composition. Examples of order in a design may be symmetrical

versus asymmetrical balance or a formal versus naturalistic arrangement.

Unity is the harmonious relationship among all elements and characteristics of a design. A unified design is

homogeneous and congruous. A design lacking unity appears disorderly and haphazard.

Too many components and materials and the complex use of the elements create competitiveness and a lack of

integration within a design. To establish unity in a design, stay simple and minimize differences. Limit the complexity

of the design elements incorporated into the design. Group the elements in groups of three or uneven numbers.

Always remember to simplify diversity and reduce the number of differences between the components in the landscape.

Repetition

Repetition involves repeating or using an element more than once throughout a design. It helps establish and add order

and unity to a design. Repetition provides a common feature throughout the design that pulls the design together.

Rhythm a nd Sequence

Rhythm and sequence describe the dynamic unity or the related, orderly movement that implies continuity. They

are the apparent flow of lines, textures, and colors that express a feeling of motion rather than confusion.

Order and repetition help establish rhythm and sequence in a design. Rhythm and sequence characterize continuity

and connection from one part of the design to another part. They group the components together, drawing the

design together. This keeps the viewers eyes busy and allows them to follow easier through the design.

Rhythm and sequence lead the viewers eyes easily and smoothly along a deliberate, dominant, and visual path.

The viewers eyes move back and forth with a feeling of smooth motion between the components of the site and

the focal point.

As a designer, accomplish rhythm and sequence in a design by repeating one or more of the elements such as line

(creating a pattern), form, texture, and color. In addition, build on the other design principles to create rhythm and

sequence in a design.

Interconnection

Interconnection is a design principle for producing

unity in the design. Various components in the design

are physically linked together. Repetition helps in

establishing interconnection. A designer may

incorporate interconnection into the entire design or

into only a small space within the design.

SUMMARY

Every design a designer creates is unique. However, the elements and principles of design are probably included

in each design. Use the design elements of line, form, texture, and color as guidelines in design development. In

addition, consider the principles of focalization, proportion and scale, balance, order and unity, repetition, rhythm

and sequence, and interconnection.
